Has anyone experienced this and found a solution?
4:3 PAL video edited with Edius V6, output as MPEG2 using Edius's inbuilt encoder, DVD authored with DVDLab Pro and burnt to a CD-R. I've checked and double checked all the possible settings in both programs.
Playing the DVD on my computer, it looks fine - via Windows Media Player, CinePlayer, PowerDVD etc.
But when I play it on my Panasonic machine connected to my widescreen TV (the player is actually a hard disc/DVD recorder), I see a 4:3 picture with the video letterboxed - i.e. the top and bottom of the picture, not squeezed, is masked out - giving a 16:9 ratio picture, surrounded by black, in the centre of the screen. The same thing happens when I play the DVD on my Panasonic Blu Ray player connected to a (widescreen) projector. This leads me to conclude that neither the TV nor the player has a problem. 4:3 commercial DVDs, and DVD-Rs made on a different computer system, play correctly on either player.
However, if I attach a (rather ancient) Toshiba DVD player to the TV, the DVD plays back correctly from that, as a full 4:3 picture. There must be something that is telling the Panasonic machines to mask out (letterbox) the 4:3 picture to make it appear as a widescreen one that the TV can be set to zoom into to fill the screen. By the way, I see the full, unmasked, menu screen, displayed as 4:3.
DVDLab Pro has a tool marked 'Fix Stream Headers' - I've tried running that, then re-compiling and burning the DVD, but with the same results.
I've displayed all the DVD parameters using IfoEdit - I don't understand most of these, but I can't see anything obviously wrong. Anything to do with aspect ratios shows as 4:3.
I'd be really, really grateful if anyone has any idea what could be causing this.
