I'll admit that I've never really played with transcoding because MPEG-2 is good enough for my purposes (I don't usually take the shows off of the machine, they stay on it until I watch them and delete them).
However, I believe that you'll want to go back into the recording profiles. You should notice that there's profiles for MPEG-2 cards, V4L (I think that's what it's called) cards, and Transcoders. Under Transcoders, there's then another set of categories for the source input (MPEG-2 versus RTJPEG), and by selecting the appropriate category, you can play with the parameters. -- Joe --- Derek Tattersall <[EMAIL PROTECTED]> wrote: > Thanks for the assistance, you've been very patient > with my questions. > That fixed it. > > So I have another question.
