The following is the basic series of steps.  Steps 2 and 3 (generating the 
XSVCD complient mpeg file) is the tricky one - especially if there are any 
recording errors in the file.

Step 1 - Record a broadcast using VDR and edit/split to files approximately 
700MB in size

Step 2 - Demultiplex using es_demux from the DVB driver

es_demux 001.vdr 001.mpa 001.mpv

Make a note of the A/V sync value  For example, 226 ms

You can also use pvastrumento (I run it without trouble under wine) and press 
"info" to display this value.  es_demux usually gives me an insane value 
(e.g. 45780.8s)

Step 3 - Remultiplex to XSVCD format (using mplex from the DVB driver)

mplex -v 226 -i ES_STREAM -t XSVCD 001.mpa 001.mpv

Where "-v 226" is the video delay.  If it is negative, then specify an audio 
delay (-a X).  The multiplexed file is called "out.mpg".

Step 4 - Create CD image using vcdimager 0.6.2 (http://www.vcdimager.org)

vcdimager -t svcd --broken-svcd-mode -c videocd.cue -b videocd.bin -l 
SVCD_LABEL -v out.mpg

Step 5 - Burn using cdrdao:

cdrdao write --device 0,0,0 --driver generic-mmc videocd.cue

The "device" and "driver" will vary depending upon your setup.

Dave.
