Hmmm, well, I don't have a PVR-x50... though I have 2 M-179s on order, 
so hopefully I'll be able to capture direct to 1/2 D1 soon.  In the 
meantime I capture to mostly RTjpeg, though I can do MPEG-4 for shows 
that I know I want to archive.  So, 2 questions:

(1) When you've transcoded Div/MPEG-4 to MPEG-2 1/2 D1, how did you do 
it (i.e., mpeg2enc?  transcode? what options? and what options for 
mplex/tcmplex ?)

(2) Once you have an 1/2 D1 MPEG-2 file (either from transcoding or 
hardware encoder), how do you author it?  I use vcdimager (well, via 
k3b) to author my SVCDs, but how are CVDs authored?  Are they authored 
like DVDs, or like (S)VCDs?  What tools do you use?

Thanks again,
