"Stretched" picture DVD. Remedy?

[konnak]

I don't know if this is the correct thread to post this, I just use the big3 method so I would be familiar to any relevant solution.
I have a 4.37GB DVD (single-layer) which has been wrongly encoded as 4:3, while it's in fact 16:9. This has resulted in a stretched picture (no bars above and below the movie picture). Whereas I can bypass this issue when I view the DVD on my TV set (by turning on its 16:9 function), I haven't found a way to view it properly on PowerDVD or WinDVD. Is there any way to make a new DVD which will have the 16:9 flag corrected, and not having to reencode the whole thing (since it already fits on an empty DVDR, and also wouldn't want to cause any additional quality loss)? Any opinion would be appreciated

PS: the DVD is movie only, no menus

dvd patcher should do the trick. it will do entire vobs (you would have to do each vob in the vob set). worth a shot. dvdpatcher is in mentioned in the svcd->dvd guide.. also should be in doom9 downloads

Well, thanks Trahald, I tried DVD Patcher, but it had no effect, so I realised that the VOBs had to be OK (also since DVDpatcher reported that they were 16:9 encoded). So I figured that the basis of the whole issue should be the IFOs. I opened them with IFOedit and...voila! The IFO had wrongly stated the stream as 4:3, and the result was the streched picture. Anyway, thanks for your help, DVDpatcher is a useful tool to have in mind in other situations.
