I upgraded from NXT Pro to NXT Pro 3 recently. With Nxt Pro, I was able to use the UB315-E capture USB devices without any problems. When I upgraded to NXT Pro 3, the video capture works fine, but the audio is horribly distorted. I tried loading a new driver for the capture device, reloaded the software, nothing worked. I am running Windows 7 on a 64-bit machine. Roxio support tells me that I can't get help until I register and get a code, I register, no code. Very frustrating. Any ideas?
