I am currently using a Samsung 709 and Sony STRDB-930. I have just watched Castaway in DTS, and again, the DTS sound track is slightly out of step with the video. However, the DD track is fine. This is the same on ALL of the DTS disks I have (i.e Gladiator, U-571 etc).. I therefore don't think that its the disks which are at fault, which means that its either the DVD player or the Amp... Does anyone else get this problem? Any idea whats causing it?
