[I.M. Nobody]

Last night I set the receiver to record 2 shows, Heros and Justice. I watched Heros while it recorded. At the first commercial I opened the guide and found that it was not recording Justice. I tried to record it by pushing the record button but it would not record. I tried another channel but it said there was a conflict.

Has anyone else had this problem did I do something wrong? This is the first Problem I'v had with recording.
