However, if you still want to get your name in our "list" of potential sites, you can do the following: send information regarding how we can contact you (email, phone, fax, and mailing address), your experience (what do you do with your computer, & what, if any, testing have you done for other developers, etc.), your equipment (what hardware do you have, what software), and anything else you think we should know. PLEASE DO NOT SEND THIS INFORMATION TO ME!!!! Instead, send it to "macbeta@radius.com". If you also have PC equipment and might be interested in beta testing PC products, send the same information to "pcbeta@radius.com".

So far, RadiusTV is just begging me to buy it; but I have some
more queries. With regard to the audio digitization feature, I
assume that it can capture sound at the "normal" MacRecorder
levels (i.e. up to 22 KHz). Does it have the capability to
capture sound at 44.1 KHz; what about custom frequencies? The
one disadvantage with most sound-capture devices on the Macintosh
is that the length of sounds is limited by available RAM. Does
RadiusTV have this limitation? It's probably not important
because RadiusTV's probably more geared to video, but since
Radius added audio...well...
A friend of mine played with a frame grabber from MassMicro (I
don't remember the company's exact name--sorry) and had
complaints about the low-resolution of NTSC signals causing
grabbed images to leave every other line blank (this is the
digitized image in PICT format). Does RadiusTV have this
problem? Will RadiusTV support other signals beside NTSC and RGB
such as PAL and SECAM (I won't have a need but it's nice to
know). Will Radius support S-Jacks in the future--I know that it
doesn't have them now? With respect to update speed, does it
take more overhead--is it slower--updating a larger screen area?
