My player is a Cambridge Audio Azur 651BD. When I played the DVD disc, it played fine all the way through until it got to Bouree (Morgan version), at which point it skipped several times but eventually corrected itself.
Since then, it hasn't happened at all - it plays perfectly each time. Strange.
I have not had any other problems playing DTS DVDs in general.
Sounds like you had a loose piece of dust (hair?) on the disc.
