We will be going to the cottage this weekend and as I have many unviewed shows recorded on my 630 I was thinking about taking it with us to use as a viewer only. I don't have a dish to connect it to so I was wondering if anyone has tried to operate it without any signal lines attached? I remember the 530 did not like this and put an nag on the screen about loss of signal or something that interfered with the viewing of recorded material somewhat. Haven't had time to experiment with this myself yet but I'd appreciate it if someone else has tried this yet. Thanks.
