Sound out of synch on TV Wonder Pro

I've got cable TV coming in. The sound is connected to my sound card with
the external cable. The sound on TV is coming in ahead of the picture.
When people speak, the voice looks way off. Any suggestions?

Don't know much about TV Wonders, jeffc, but in their more recent
driver releases, ATI have changed to using digital sound: one of the
effects of this is that sound _and_ picture are delayed behind the
received signal. looks like you may be getting the delayed picture
but, because you're inputting the sound through your souncard, not the
delayed sound. At a guess, recordings will now come out with no sound
at all, if done with ATI's software.

If there's a way you can input the sound directly to the TV Wonder
rather than your soundcard (i.e. via a dongle or adapter) that should
fix it; otherwise, if this _is_ the cause of your problem, you need to
revert to an earlier driver that uses analog sound.

When you installed the drivers and software you're currently using for
the card and ran the Initialization Wizard when you first started it,
did it give you an option to select a sound input? If not, then
you're on a digital driver.

Please bear in mind that this advice is transferred from AIW use: I
don't actually know how this parallels to a TV Wonder. But it seems a
possible explanation.

On my Hauppauge card, when you view tuner output, what you're
actually seeing is an MPEG encoded signal. If you bring an external
signal in from another source, say from a VCR, the audio is ahead
of this encoded video signal by about 1 second. The "fix" is to
enable LivePreview (a registry hack for the Hauppauge, not sure
if a similar one is available for the ATI card), so what's displayed
is the pre-encoded signal (without the delay caused by the MPEG
encoder).

Hope that makes some sort of sense, and is relevant to your problem.
 
I had same problem with my ATI 128 AIW card. Tried everything. Then
after help from others on this newsgroup, I found it was the clock on
my el cheapo sound card was out of tolerance, and when you did a
capture the Audio/Video would end up out of sync. When you install
the ATI card it runs a test and generates a report, and sure enough
when I looked back at mine it said the sound card clock was just a few
hundreths of a percent out of tolerance. Switching to a Sound Blaster
or other quality card can help to get it closer, but it may still
drift out on long captures. You have to use a capture card that has
built-in Audio inputs where the audio is locked to the video during
the capture. There are several ot there, and I bought one but can't
remember the name at this time, but in addition to Video it also has
two audio inputs on the card and the audio is locked in to the video
by hardware on the card. I think the card was in the $120 range and
it works great for analog capture, but you would have to feed both
video and audio from your ATI card into this other card
