Last night I turned on my HR20 to find a blank screen. I hot info and all the channel type information was blank. Same with More Info. I exit it out and tried previous channel - nothing. I changed the channel to USA and L&O:SVU came up. I again tried previous channel and it went to 294(Not sure what that is off the top of me head). After that everything seemed OK. I've also noticed when coming out of a couple of shows off the DVR that the channel is on 201. I've never turned to channel 201 previously. These have only popped up since this patch.
