Page 1 of T2: Judgement Day

I have a Toshiba SD 2109 connected to a Videologic Digitheatre DTS system. I have watched this excellent film with the DTS soundtrack but noticed that at the beginning when the THX intro is played that the sound is broken and this also happens at odd intervals throughout the film. Has any other person had any experience of this as the film appears to play fine when the DD 5.1 soundtrack is selected. Any information would be a great help because if the disc is faulty Play247 have told me they will replace it.

Watched it all the way through with DD and its fine. However Chris Cox (our resident R1 news hound) has also had problems with the DTS and his Pioneer.
