I just bought one here in Seattle for $399. It's a basic machine but it does have a picture that is a substantial improvement over standard VHS. The machine has a some "features" that undoubtedly help JVC offer this unit at so low a price: 1) The remote control is detachable and doubles as the front panel controls. If you lose or break your remote control, you're out of commission. 2) Though cable-ready, there are only 12 channel presets. 3) The machine records only in the "SP" and "ELP" (2 and 6 hour) speeds. The "SLP" (4 hour) speed has been omitted. Quality in the ELP speed is about as good as a standard VHS deck in the SLP mode (which is to say, bleagh!).

Sorry to butt in, but a little lesson in VHS speed terminology is needed. SP - Standard Play: fastest possible speed LP - Long Play: 1/2 SP speed SLP - Super Long Play: 1/3 SP speed EP - Extended Play: another name for SLP JVC has never supported recording in the LP mode. But they do play it back. So, your deck has the SP and SLP/EP speeds for recording and the SP, LP and SLP/EP speeds for playing back. I have been through 3 JVC decks (currently have one of them) and they all play back LP, but do none of the special effects in that speed. -- ihnp4------\ harvard-\ \ Mr. Video seismo!uwvax!nicmad!brown topaz-/ / decvax------/

Just for the record, NO JVC VCR made in at least the last 3 years (maybe more) RECRDS in LP speed, not even the top of the line models. --------------------------------------------------------------------------- Jim Block {cca, ihnp4!inmet, mit-eddie, wjh12, datacube} !mirror!prism!jib Mirror Systems, Inc. 2067 Massachusetts Ave. (617) 661-0777 Cambridge, MA 02140

The luminance and chrominance averaging ("noise reduction") was not included. However, on the HQ machine which I tested, turning on the noise reduction did little (if any) improvement (at SP), so you got the best part of the package. FLAME ON: It seems that JVC is lax on what is HQ and what is not. The package does not ALL have to be included to be termed HQ. Plus, the phrase HQ has not yet shown up on any front panel that I have seen. Talk about market confusion.... FLAME OFF. --Kne

If it is worth seeing, it is worth seeing well. We find that we have to buy the most expensive decks available just to be beta-scan (or equivalent in VHS) at the high speed. JVC does not support this on any deck! Amazing! What does it take to give special effects at a particular speed? Does it really cost a lot extra? FLAME OFF I don't know if NTSC is the best television in the world (-:), but I do know that mom and pop have a lot of fecal contaminants on their 6-hour tapes recorded on no-name stock. --Kne

All three of the JVC decks that I have had and still do have one of them, supports special effects at the SP and EP speeds. I didn't know that JVC DIDN'T support special effects at the SP speed. I too like quality, which is why I record at the highest speed (SP). The machine that I have (HRD-725U) has special effects in the sp and EP speeds. The other machines that I had, the HR7650U and HR2650U, both supported special effects and the SP and EP speeds. I don't know what JVC machines that you saw, but they obviously weren't the ones mentioned here. True, the decks that I bought were not the bottom of the line. All three are Dolby stereo and the last (HRD-725U), is HI-FI stereo as well. Not cheap. But, to make a statement that JVC doesn't support special effects on any deck, is wrong. My FLAME is now OFF. -- ihnp4------\ harvard-\ \ Mr. Video seismo!uwvax!nicmad!brown topaz-/ / decvax------/

However, you mentioned in your posting that special effects were not supported, then flame that they are. Which is in error? What I was referring to in particular was the ability to high-speed scan with the picture "clear", not rolling on the screen, at SP. In the beta world this is called beta-scan. I don't know what VHS calls it. On the JVC 566 (give or take some letters), the picture is clear at EP but not SP. On various other JVC's I have seen, the same holds true. In fact, on most VCR's, I find that this (particular) special effect is reserved for one speed only, and that is the slowest speed. (Yes, still frame, frame advance, various slow motions, etc. were supported at all speeds, if any speeds were supported.) The specific question is, what does it take to synchronize the tape to allow "clear" high speed visible scan rather than rolling jumble. It is really a lot? I DON'T KNOW. THIS IS A QUESTION, NOT AN ACUSATION. --Kne (Never forget errors induced by differences in perspective...a crowded elevator smells different to a midget.)

On my JVC deck fast scanning is called Shuttle Search. The HRD-725U has better picture when SP search is used, both forward and reverse. This deck uses a special technique of switching the 4 video heads so that the strongest signal is switched through to the tv. It has the effect of displaying the SP then EP then other SP then other EP head. In the EP mode, only the EP heads are used, which causes more noise at the head switchover points. After reading your point about your TV rolling, a thought came to mind, ie, does your TV have a vertical hold control? If not, that may be where some of the problem lies. I have noticed on tvs that do not have the vertical hold, they tend to lose vertical sync when a video deck is scanned. A deck that I had worked fine on my TV (w/ hold) and rolled on a Zenith tv, which doesn't have vertical hold. Since fast scanning does cause some change in the vertical rate, some tvs lose vertical sync. So, picture rolling, when in fast scan mode, is normally caused by the tv, not the video deck. I suggest trying your deck on a friend's tv that does have vertical hold. As a little side note, I can set my tv's vertical hold so that it is ok on normal picture, but will roll when fast scan is used. Adjusting the hold again takes care of the problem. I am interested in reading what you find out. -- ihnp4------\ harvard-\ \ Mr. Video seismo!uwvax!nicmad!brown topaz-/ / decvax------/

Since fast scanning >does cause some change in the vertical rate, some tvs lose vertical sync. > It isn't this. At EP speed everything works as expected. I have noticed that on most non-top-of-the-line decks (beta and VHS) you get rocksteady shuttle-scan/beta-scan at only one speed, like it is too difficult to synchronize the tape speed/head switching to switch properly. Rather, just run the tape at some speed and switch the heads when they loose contact with the tape. If the tape is not running at some integral multiple of frames (or fields maybe), the heads switch at some random location in a field and the picture rolls up/down/left/right/pincushion distortion/ barrel distortion, and all sorts of mean nasty stuff. It would "only" require, I think, controlling the tape speed to be a stable multiple of normal. (Decks with knowledge: Sony 900, NEC 739E (stable at both speeds) Sony 400, Sanyo 7250, JVC 566 (stable only at low speed). Oh well, I think this topic is now talked to death... --Kne

There are also at least three other new models of VHS VCR that incorporate the HQ circuitry that you might be interested in. I just got a NEC 961 that has HQ and am so far very happy with it. I've only had it less than a week though. Cannon and Yamaha both make HQ models, too, but I don't have the model numbers with me right now. -- Dave Johnson Dept. of Computer Science Rice University UUCP: {lbl-csam,cbosgd,shell,convex,sun,texsun}!rice!dbj ARPA: dbj@rice.EDU, dbj@rice.ARPA

When I submitted my message a while back about the NEC, Yamaha and Canon VHS HQ models, I didn't have the model numbers for the Yamaha and Canon ones in front of me so I only mentioned the NEC model number (the 961). Well, now that I'm thinking of it again and have the information with me, I'll give you those other two model numbers. The Yamaha YV-1000 and the Canon VR-HF600 both have HQ. The Yamaha has built-in MTS stereo, but the Canon requires an outboard MTS decoder (Canon makes one, the MS-10). -- Dave Johnson Dept. of Computer Science Rice University UUCP: {lbl-csam,cbosgd,shell,convex,sun,texsun}!rice!dbj ARPA: dbj@rice.EDU, dbj@rice.ARPA
