its no wonder you can't play the file in synch even with your powerful P 
IV Prescott CPU. This is one of the very rare test files in HD-TV 
resolution (1280 x 720 pixels !), using the extremely CPU consuming 
h.264 (AVC) video compression format. I wonder who is distributing such 
stuff without very clear advice to people on how to play it, and what 
the minimum requirements for hardware are.

DVD Santa won't work here, because the picture input resolution is 
higher than DVD standard (720 x 480/576 ; read my comments in the Guide 
again - it should have been clear to you).
I recommend to either look at Mediacoder (http://mediacoder.sf.net) for 
the MPEG conversion to DVD, or to learn how to use AVIsynth as a 
scriptable input converter including downsizing of the picture 
resolution into other programs, accepting AVI input. Doom9.org is 
usually a good source of information here.

P.S. Its possible that by using VLC http://videolan.org or the great new 
CoreAVC DirectShow filter from http://corecodec.com for fast AVC 
decoding your movie will play fina and in synch.
