My 510 works great in analog mode. But i can only watch 5 minutes of hd video. The unit will lose signal with the TV. Also, while switching from analog to digital mode, I have to do it at precisely the correct time or else I will not get a signal. I have 1.08 installed and it still does it. I own a Mitsu 57733 tv. I have installed my hd dish receiver into each hmdi input and they all are working correctly. Any chance there is a fix out there? I cannot downgrade software, as the unit will not allow it. Thanks in advance for any help!!
