The attached patch fixes the jerky playback of VC-1 content with pulldown. The pulldown flags were incorrectly set. They must be correct in order to display the frames with the correct timing as mentioned in the specifications: "SMPTE 421M: VC-1 Compressed Video Bitstream Format and Decoding Process". More precisely the following tables: Table 20: Progressive P picture layer bitstream for Advanced Profile Table 22: Progressive B picture layer bitstream for Advanced Profile Table 23: Progressive Skipped picture layer bitstream for Advanced Profile Table 82: Interlaced Frame I and BI picture layer bitstream for Advanced Profile Table 83: Interlaced Frame P picture layer bitstream for Advanced Profile Table 84: Interlaced Frame B picture layer bitstream for Advanced Profile Table 85: Picture Layer bitstream for Field 1 of Interlace Field Picture for Advanced Profile Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
