No Digital Audio with New Firmware

Every time I try to upgrade my firmware, I try to play a video with DTS audio I get no sound. The sound will play in “Stereo” mode (as opposed to “Digital”) but the whole reason I used DTS is because I wanted surround sound. With firmware version 1.02.21 the audio played fine. With version 1.03.49, 1.04.10_V, and 1.04.17_V “Digital” gives me no sound. This is extremely frustrating and I desperately need the fixes that have been included in the new firmware, but it doesn’t do me much good if I lose my sound…

If you update to the latest firmware, are you able to play your movies with digital audio?
