[MEncoder-users] Progressive Scan DVD player?

[Andy Civil]

I apologise for the slight off-topic nature of this, but I think the skill set 
of the friends here is appropriate: I'm trying to get the best out of my 
Progressive Scan DVD player (it's actually a DVP3140). I've tried using 
tfields=2,scale=720:480,harddup to make a 60000/1001 divx stream, but my player 
ignores it - I'm assuming that it can't actually decode a 720p60fps stream, but 
requires a 720i30fps stream to work. The thing is, if I let the DVD player 
upconvert this to 60fps in progressive scan mode, that's no different from 
letting the TV (an LCD display) do it, is it?

If I can't actually play a full frame (720) at 60fps, then I'm not going to get 
any better quality than a regular DVD.

Without expecting anyone to know my specific player, has anyone discovered the 
best kind of stream to use with MEncoder for DivX capable players in general?

Also, has anyone experimented with better-quality players that are not 
necessarily HD-DVD or BLU-RAY but can accept superior streams written to DVDs 
(maybe without the ~10,000kb/s data rate restriction)?

Thanks
