Well, since I only used my own player I'm not sure how good of a 
datapoint it represents but I used to use mplex to produce SVCDs (in all 
I probably created about 50 of them) and they worked just dandy in my 
standalone player, a Pioneer DV 343 if I am recalling correctly what it 
is. Before that I had a super cheap-o Raite AV-Phile thing which to tell 
you the truth was a very solid player that handled everything smoothely. 
It got zapped in a power surge or something and that's when I went to 
the Pioneer.

The 'real' specifications are not freely available (you have to pay for 
the standards docs) although with a clever google search you may be able 
to turn up draft specifications. I happen to own a copy of the svcd spec 
so if you had a more specific question to ask (what bit rates are 
allowable etc.) then I could try to answer those questions.

Sounds like you do know how to test it! ;-) I would burn a copy and give 
it a try in my player.
