I also thought it was just the overscan but I have created many SVCD’s previously and transcoded from Xvid to mpeg2 using Tmpgenc with no picture loss around the edges (that is noticeable).
So it seems it is just the DVD’s created in Encore. I may try and put the same mpeg2 file into nerovision and build the DVD from there and see if I get the samee effect.
Thanks for your reply.
