[mythtv-users] PVR-350 mpeg2 --> DVD burning. No commercial cutting or fancy stuff.

	I've been relatively frustrated with the experience, myself... but I 
did manage to make one SVCD go using the following steps:

- strip the audio 
	'mpeg2desc -a0 < infile.nuv > temp.mp2'
- strip the video
	'mpeg2desc -v0 < infile.nuv > temp.m2v'
- resize the video (by 1.5x e.g.)
	'tcrequant -i temp.m2v -o temp_crunched.m2v -f 1.5'
- resample audio for 44.1kHz SVCD-complient mp2
	'mpg123 -s temp.mp2 | sox -c 2 -s -r 48000 -w -t raw - -r 44100 -t wav - | \
	        mp2enc -b 192 -r 44100 -o temp44.mp2'
- recombine into SVCD-friendly stream
	'tcmplex -N -m s -p temp44.mp2 -i temp_crunched.m2v -o temp.mpg'
- Cut out commercials with GOPchop
	'gopchop'... plus gui-isms -> temp_cut.mpg
- master SVCD image
	'vcdimager -t svcd temp_cut.mpg'
- burn image
	'cdrdao write --device 0,6,0 videocd.cue'

Boy... I forgot what a royal PITA this was!  It did, however, result in a 695 
MB standards-compliant SVCD with 43 minutes of video with SP-VHS quality.

	Doing the GOPchop after the requant was necessary, as it currently 
appears to break the audio streams so stream strippers don't recognize them.

	Haven't gone down the DVD road yet.  Right now I'm thinking of trying 
to modify the procedure to make a 'mini-DVD' (e.g. DVD format on a CD), using 
1/2 D1 size of 352x480.  That should be easily scalable to full-sized DVD's, 
and probably just about as compatible with set-top DVD players.  So far my 
experience with SVCD compatibility has been underwhelming.
