AIW 7500 Sound

[Steve P]

I've got an Biostar M7NCD Pro running an AMD 2500+ chip with 512M RAM and an
AIW 7500. I've noticed that the sound of my captures from TV are not
anywhere near as good (it sounds like 8 bit sound) as the sound I hear when
watching TV on the computer. I've found a little info on this at
http://www.jimrothe.com/htpc_troubleshooting.html . I'm running MMC 8.7 and
Windows XP.
Should 256K Bits/sec for sound be sufficient?

Is anyone else having this problem?

I have the same problem and have asked the same question again and again but
no one knows the answer. My system is great with MMC 7.7 but the sound are
like 8 bit to me after updating to MMC 8.7. I did a clean installation and
had the same result. My system is Celeron 1.1A, AIW 8500DV and Win 2000.

I have a similar setup, but I don't have v-8.7 of MMC. Mine came with v-
7.5 of the software, and the ATI site says I can't download the upgrade.
Since v-7.5 works fine for my purposes, I chose not to spend $20 for the
upgrade on CD.

I have noticed some periodic chirps in the audio when using the MMC-7.5
software so I don't use it. I have tried a number of different capture
programs. I wanted to use VirtualDUB since it is freeware but it only
seems to capture to huge AVI files. I tried Adobe Premiere but it does
not recognize the ATI-7500 as a capture source. I have settled on doing
my capturing using Ulead software. If I am capturing something to put on
a VCD or an SVCD or a normal DVD, I use Ulead DVD MovieFactory 2. It is
simple to use and does a good job with capturing, trimming, etc. If I am
capturing something from TV that is not DVD quality, I use the "Video
Capture 7" utility that came with "Ulead MediaStudio 7". I set it up for
352x240, 29.97 frame-rate and 48,000 16-bit stereo. By doing it that way,
I can use "TMPGEnc DVD Author"to create the DVD and the DVD will hold a
lot more than the 720x480 standard for DVD's. It is like a VCD .... only
stored on a DVD with it's 48,000 audio.

I went in to the initialization wizard (start the TV, press the setup
button, and select initialization wizard) and played with the audio
selections and the TV record seems to work much better now.

It has something to do with this...
