Most of the videos I download are via Revision3.Com They offer many formats in small and large file sizes including WMV, XVID/AVI, MOV and their flash player in low and high. I was using a Pocket Pc and the small WMV worked great without conversion. The N810 chokes on the small WMV, but plays great after conversion with NITVC. The funny thing is the converted file is still a wmv and about the same size. Not sure why the N810 chokes on the Rev3 video other then they may use different codec when encoding that N810 doesn't like. My next goal is to eliminate as many steps in the DL to PC, conversion, copy to shared PC folder, and upload to N810 via wifi. I'm hoping I can stream the converted file right into N810's player.
