I had a slice upgrade to 6.4a go south on me and now the only way I get video is to record the program??? Anyway, can I just copy the root and active partitions, leaving the media partitions alone, from a working unit on to the bad drive and have a working drive with the old recordings? Can it be that simple??? Or, does somebody know something about only having live video if recording the program? It's not the unit. I have tried several and the problem remains, regardless of which HDVR2 I install it in. Thanks.
