Moth3r said: Really? I've never seen a DVD that implements the 4:3 Pan & Scan option. A "centre of interest" offset is supposed to be encoded in the video stream, otherwise you just end up with the sides cropped and the scanned window stays centered (does not "pan").

I assumed that the behavior was a response to a sequence_display_extension of 540x480 being written in the MPEG-2 header info, which probably means that I inadvertently set the colorimetry in HCenc (which I shouldn't have done). I doubt that I flagged the VOBs themselves as 4:3, but I suppose it's possible.

I understand what you mean about forcing letterbox mode if the player is set to P&S now: if one doesn't encode a centre of interest then you have to do this or in P&S mode there is no panning.

EDIT: Moth3r, how do you determine whether a centre of interest has beeen encoded into the MPEG-2 stream? Restream doesn't seem to show it.

I'll PM Harmy for the links to the DVD and AVCHD and take a look, and if necessary re-author the disc, but most commercial discs that I test seem to have a sequence_display_extension of 540x480 if they take NAB into account.
