That's by design. You can navigate only to random access points, i.e., IDR frames or recovery points. When you position with the trackbar, it will then search forward for the next random access point and decode and display one frame starting from there, finally setting the trackbar position to that point. So, if your GOPs are big, you will see behavior like you describe. You can cut only at GOP boundaries anyway, so it doesn't adversely impact cutting.

DGIndex works the same way, but in MPEG2 people don't often make large GOPs like we see with AVC.
