Boot version 120B Flash version F051 SW version L145HECD-N System becomes unstable and crashes in 2 situations: 1) if a OTA digital program is recording from the background timer and you try to go to one of the OTA digital channels to view by direct channel entry (even the one that is recording). I get a blank black screen or grey screen. The system seems to become unstable after that point and within 5-20 minutes crashes. If this is a system limitation them I would think the conflict screen would come directing you the the station being recorded or stopping the recording. 2) If 2 Satellite channels are being recorded and you try to goto to one of the digiatl OTA channels to view a live program you get the same thing as stated in #1 above. I do not have any analog channels loaded in on OTA so I do not know if the same thing will happen with analog channels.
