 Playing certain DVDs (MPEG2  720x480  (aspect 3)  29.970 fps  8800.0 kbps,
 under mplayer) after ffmpeg commit 8824a9ed "mpeg12: clean current picture
 ptr." results in many error messages:
 [mpeg2video @ 0xf404a0]first field missing
 and blank video.  (Audio continues to work fine.)

 Reverting this commit fixes the problem and video plays perfectly with the
 following messages:
 [mpeg2video @ 0xf404a0]allocate dummy last picture for field based first
 keyframe
 [mpeg2video @ 0xf404a0]ac-tex damaged at 7 6
