Image is stretched vertically

[Hansomfiser]

I'm trying to burn a .MPEG file which plays just fine in my computer but when I burn on SVCD the image is stretched like an inch vertically in my TV. I checked it with some DVD author tool or something and it was 16:7 but it plays fine in my computer. But there are small borders to the right and left of the image in my computer, which usually wont appear on other wide screen movies. The borders should be at the top and bottom only??

I insert a screenshot to show you guys how it looks.

How can I fix this?

You mean 16:9? Well the answer it simple. The 16:9 aspect ratio flag is not supported in the SVCD standard, so the player will not recognize this flag and do the resize to the proper aspect ratio. It will look fine on your pc, just not when played via a dvd player. I think you may have to re-encode to 4:3.

The letterboxing on the sides looks like someone just tried to compensate for overscan. That area of the picture will not be seen on a tv because the outer edges are cropped/rounded off, so if you can't see it why waste bitrate for that part of the picture? So you add letterboxing here instead since it takes alot less bitrate to encode all black then to encode actual picture. This shouldn't have any effect on your problem.

adam : thanks alot for your reply.

How shall I re-encode it to 4:3? And will it still look fine on my compter when the mpeg file is re-encoded to 4:3 from 16:9?

It's in mpeg so I can't use TMPGenc.

Well you could load it into TMPGenc by increasing the direct show file reader's priority (if you can play it, you can load it this way) but I don't recommend that. You would be best to frameserve through dvd2avi. I think the easiest thing to do would be to follow one of the DVD->SVCD guides and just substitute the word "vob" for mpg. As far as your conversion process is concerned, there will be no difference.

I would, however, first demultiplex your audio stream from your mpeg. Then go ahead and encode the video to a video only stream (bottom right option in TMPGenc) and then you can remultiplex your streams together after this. (file/mpeg tools/simple multiplex.) Otherwise, you will end up re-encoding your audio too for no reason.
