J7N is an unknown quantity at this point

MPEG-4 and WMV have much fewer keyframes than MPEG-1 or MPEG-2 and higher complexity, so seeking is harder. The Group of Pictures (interval between keyframes) in MPEG-2 is at most 18 frames, while in next-gen formats, including commercial Blu-rays, the interval is usually between 100 and 250 frames.

Nevertheless the system should be able to resync quickly after seeking. If it does not, then it's not operating properly. It takes 4-8 seconds to jump in Blu-ray streams on my computer, but still playback resumes normally.

I can seek allright with this combination:
- Haali Media Splitter, 2007-06-03
- ffdshow beta4
- AC3Filter v1.01a
- BSPlayer 1.36 (occasionally crashes if there are subtitles)

I've found that the later versions of AC3Filter perform poorly during seeking (sound goes on and repeats a small buffer until video catches up).
