The preview pixmap generate will ignore PreviewPixmapOffset? in lots of cases. It also takes into account RecordPreRoll?, PreviewFromBookmark?, the commercial skip list, and the cutlist, so there are lots of reasons why the image would not always be from a fixed position in the recording. Closing ticket unless you can document cases where it's not working as it should. Unfortunately, "pretty odd sometimes" doesn't help us debug. If you want to try to track this down, edit NuppelVideoPlayer?.cpp and search for NuppelVideoPlayer::GetScreenGrab?() and insert some lines like the one below every time you see the 'number' variable modified. Then you can see why it is choosing the frame it chooses.
cerr << "NVP::GetScreenGrab?: Line: " << LINE << ", number = " << number << endl;
That will print out the current value of number and the current line number as well so you can see where it is being changed at.
mythweb just requests the pixmap, it doesn't generate it. this is a backend issue (though I've never had a problem, myself).
