I originally posted this in the dshowhelper development thread, and I am quoting it here. I had installed tsreader 63b in October, and have now reverted to 59c. No logs available, so the report is probably worthless, but here goes. The problem is unpredictable (to me), but may be related to viewing a recording while comskp is running on the program -- some instances I can remember were in that circumstance.
". . . the skip functions are quirky! Sometimes the skip is clearly not the amount intended, and sometimes (I swear!!) they appear to go in the wrong direction! A typical sequence: skipping a commercial, I go too far forward (into the program), and skip back less than I skipped forward and find I've gone too far backward. Skip forward again the same amount I skipped backward and still land in the commercial sequence with many seconds left to go. This is not repeatable, but happens frequently. It may be related to comskp running at the same time, but I haven't figured that out -- what would happen if auto-skip was enabled and the skip-file happened to be updated while being used? I never noticed any such effect before -- only recently."
