George2- Thanks for making that clear.
I tried recording in the same format, with the same card, just to see if it was a fluke. It was not- same bad results at 1:01.
Next I dialed it down to 24/48 w/ the same 8gb card- the recording went to 2:04, then the same digital clicking came on. I noted, though, it was not visible on the led levels.
Hoping it was just the card; I tried a 4gb card at 24/48. It recorded up to 2:04- then the noise.
I'm currently trying a recording with the 8gb card in 16bit.
Kinda bummed out; thinking it might be an issue for Oade bros.
