     Whoops, I forgot to mention in my first responce to this message 
that I tried '-npp lb' and '-npp de,lb' with these DVDs with the 
telecine artifacts.  While it does make the telecine artifacts 
*appear* to go away, it creates some other artifacts ('-npp lb' looks 
better than '-npp de,lb') that I can't quite explain, but it is very 
likely that it is due to my slow CPU.

     Adding post processing drives the CPU/Video Card requirement 
for smooth DVD playback up above my Intel Celeron 500mhz/i810 
(shared memory architecture).  It only plays for a few minutes before 
a "DEMUXER: Too many video packets" message, and an "a52: CRC check 
failed" message, at which point the audio goes away.

     Could inverse telecine be implemented as a post-processing 
option?  I'm not sure how the post-processing works, but IVTC would 
have to do things with the frame rate, and operate on two frames 
before displaying one.
