Now that wasn't what I expected. I just tried the same thing - I
didn't get the same problem. But I did get sync slippage - bad sync
slippage. I was getting all sorts of nasty BLANK messages with disc
activity too.
I've had my box open and moved cards around since the last
recordings were made - this is starting to smell nasty and PCI ish :(
I'm not in the mood to take this beast apart tonight - but soon!
