I have already produced quite a few SVCDs with the Linux-only process described
on my home page:

http://www.pxh.de/fs/svcd/index.html

The same software could be used for VCD production with different parameters.

With my process I was able to preserve sync. There have been reports, however,
about sync drifts (video and audio slowly getting more out of sync) during the
recoding. These might be related to specific broadcasts where audio packets are
left out by the encoder or lost due to bad reception (maybe my CATV reception
is more reliable then satellite broadcast, so I don't see this problem). If you
demultiplex audio and video for separate treatment, synchronization is lost.
There is a Windows tool called PVAinstrumento (http://www.offeryn.de/dv.htm)
that is said to repair such streams.

Warning: The last time I made a SVCD the recording was done with VDR-0.72 and
DVB-0.8. I haven't tested yet with the new CVS driver and the new VDR-0.8.
