[mythtv-users] What video cards *DO* work with closed captioning and audio time stretch?

[Daniel Segel]

I'm currently using a PVR-350 for both in and out of my MythTV box, and 
while the video quality is great, the Closed Captioning and audio time 
stretch features don't currently work for me (even with the latest ivtv 
drivers.)

So what's the best option if I want to make cc and time stretch work? Do 
I need a new video-out card, a new capture card, or both? What models 
will support those features and also have really high-quality 640x480 or 
720x480 output?

Specs:
MythTV 0.18.1-r2
Athlon XP 1700+
Gentoo linux w/2.6.10-gentoo-r6 kernel
ivtv 0.3.6-o
ivtvdev 0.10.2
NTSC system

Thanks,
Daniel
