Are you using the BDA drivers?
I also have a lot of expensive with this card. The chip / card is excellent, but the drivers from Terratec are shocking.
I hacked a driver pack together from the E700 (same card from a different manufacturer) to work with the DT2400i. All the signal dropouts I had instantly vanished, and every other issue.
I'll try and dig them out next week if you feel ...
