OK, I hope to try it on Monday.

Yes, makes perfect sense and it's the reason I gave up last Spring.

I've thought about that, but I have no idea what values to try for the video & audio pids. For the few channels I have, the video pids range from 64 to 7217 and the audio pids are video pid +1. It would be nice if silicondust.com's web site had that info, but it doesn't. Can you suggest some reasonable values to start with?

Thanks,
