Page 1 of Trouble with Region 1`s

I have a Grundug gdv 220. I use region 1 discs regularly, but they seem to have lip sync problems on some of them. I have played them on my brothers grundig 210 to see if it is the disc, but it clearly isn`t. Region 2 discs seem much better. The ones with lip sync problems seem to be better when played in Dolby Digital rather than on DTS. I find that very annoying because i personally think DTS is a much better sound.
Can anybody give me any ideas on what i can do to make Region 1`s play better with less lip lip sync problems.

Thanks

Juninho,

I occasionally saw lip sync issues particularly with DTS tracks on my old Matsui 110, this was always easily fixed by doing STOP/RESUME then PLAY, seems it always put the video and audio back in sync.

I don`t have such problems since I got my 750S, but the workaround for the Matsui worked a treat - maybe worth a go to see if it helps the Grundig.

Cheers

Chris
