format=xsvcd.
In order to make the gop structure svcd compliant the keyint should be
15 for pal and 18 for ntsc, although very often much longer gops play 
correctly
(I always used 25 without problems).
Please, mention also that the resulting file
- is an extended svcd (that's why it's called xsvcd), mainly because it 
doesn't
contain scan offsets
- it should be passed to vcdimager to generate the svcd image
