Fix VC-1 playback with pulldown content
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
