Greetings...What determines whether a Standalone player plays a SVCD in Letterbox mode? Is it the player? The way the SVCD is encoded? The way the SVCD is burned?

The reason I ask is that I have been having success creating SVCD's with ULead's Movie Factory. I have created a SVCD in Movie Factory using both an AVI imported, encoded, and burned in Movie Factory. I have also created an SVCD burned in Movie Factory from a mpeg-2 file created using TMPGenc's NTSC SVCD template. In each case, the svcd plays in letterbox mode on my pioneer DV-440.

I never usually specify Letterbox in the player's setup menu. The player seems to detect whether the DVD is encoded for letterbox or Non-letterbox format.

So am am guessing that the encoding is the trick. If that is so, does anyone have any suggestions what changes to the TMPGEnc NTSC SVCD template I need to make to guarentee a non-leterbox format? Or are their other ways to burn the SVCD to get full screen?

Any direction would be appreciated.
