Recently upgraded from an Hr24 and 2 h25s to a HR54 and 2 minis. Since the install I notice on all 3 that ill be watching a channel and it will freeze in place. Sometimes for 10 seconds sometimes a minute. No error code or nothing. Then it will be good for a bit and happen again. It corrects itself. Sometimes I change channels and it will be ok right when I do that. But eventually will happen again. Never had this issue with the previous receivers
