Hmmm... 
I'm by no means an expert, but i've heard people saying that the
"non-standard" SVCDs will actually play just fine on most standalone
players. 
I did a bit of testing myself, and indeed my SVCDs can be played almost
anywhere.

But isn't "lower" supposed to be "better"?

The thing is, i like to be able to control the length of the resulting
MPEG stream by controlling the bitrate. This way, i can fill up a 700MB
CD with exactly one 30 minutes cassette, and the quality is outstanding.
If i use standard SVCD, the bitrate is lower and of course i get
artifacts, etc.

Yes, good idea, i'll try that.
