I have two DVD-Audio discs from Naxos (Bach's Mass in B Minor and Rachmaninov's Piano Concertos Nos. 2 and 3) which have developed a problem. I play them on my computer with Logitech 5.1 Z-5500 speakers which have their own external DTS decoder. I'm using PowerDVD. I never had a problem until recently. All of a sudden if I play either disc in DTS mode, it sounds very choppy. Works fine in direct mode or in AC3 5.1. I don't have any problem playing movies which have DTS. I tried using the DTS decoder on the sound card (Sound Blaster Audigy 2ZS Platinum) and the external decoder and both show the same problems with these two discs only. Any ideas?

it sounds very choppy.

Define "choppy" please...

It sounds like it plays for 1/2 second and then 1/2 second pause and then 1/2 second playing and then and on and on. Almost gives a sound like static. Hope this helps.

Does this happen in stand-alone players, or only on your PC? (I'm curious, in part because I'm awaiting delivery of the Mass in B Minor and hope it is not a general problem with the disc, though I'm unlikely to use the DTS tracks. I'd still like to know if the problem is gear based or disc based).

It happens on my PC. I don't have any stand alone gear that can play DVD-A with DTS. Like I said before, other DVD-A discs work ok and the two NAXOS discs used to work ok but now they don't. I think it's NAXOS disc issue...although it may be a problem limited to certain players.
