mplex is NOT a "conversion" or encoder!
Did you ENCODE to SVCD bitrate? You have to specify -f 4 to
the encoder (mpeg2enc) AND the multiplextor (mplex).
It sounds like you took a file encoded for DVD and asked mplex
to convert it to a SVCD.
Won't work. DVD frame size is 704xN or 720xN or 352xN but NOT 480xN
(where N is 480 for US and 576 for Europe). SVCDs are 480xN and thus
you need to scale the data appropriately (y4mscaler) and then encode
with -f 4.
Once the data is successfully encoded to SVCD rate and frame size
then mplex -f 4 will work as expected.
Cheers,
Steven Schultz
