 Replying to [comment:8 cehoyos]:
 > Sample uploaded to http://samples.ffmpeg.org/ffmpeg-
 bugs/trac/ticket1438/timestamp_wrap.vob
 > The sample is approximately 4:21 and contains 4 timestamp wraps. The
 segments are about 63, 54, 57, 66 and 21 seconds long. mplayer -demuxer
 mpegps seeks fine, mplayer -demuxer lavf and ffplay seek badly.
 > ffmpeg -ss 16 (and below) works approximately correct, ffmpeg -ss 17
 jumps to a position 4,5 seconds before the end, -ss 22 fails accordingly.

 timestamp wraps in mpeg can occur at a maximum of once every 26.5...
 hours, if you have 4 in 4 minutes they are not (all) timestamp wraps.
 There are 2 seperate things here
 1. timestamp wraps
 2. timestamp discontinuities
 Please open 2 seperate tickets for these 2 seperate issues
