I'd just like to chime in and say that I too see this on one of my 
frontends. It was a P3 666 (or thereabouts) that had no problems with 
playing anything I had (all SDTV), until about a month or so ago (I 
know, not a very specific time) it started having the same problems. 
I've played with different settings (XvMC, libmpeg2, etc) de-interlace, 
don't de-interlace, etc. I even upgraded to GigE and a 1GHz processor, 
and if anything, it's worse. WAF is taking a beating, since this is the 
one she uses most often. I am always on current SVN, give or take a few 
days. I'll try different combo's of buffering, just to see if there is a 
difference there.
