I'd suspect that you'd still have the buffer for the foreground tuner. The background buffer would be lost since the 2 hour limit has passed..... buuuut ..... this isn't like Tivo where I can turn on the receiver in the morning and have one hour of programing available on each tuner to go back over, right ? ( Not complaining, just clarifying. )

Hmmm, maybe a universal remote that has a timer macro would help. Set a macro to fire a remote command every 115 minutes.
