Big night for the mythtv box

Tonight I checked mythweb and 4 out of 5 tuner are currently in use. I am not watching anything on it right now but it is recording 2 hd shows and 2 sd shows. Load on the server is .05 most of the time. It is using about 5% of the cpu. A slave backend is currently flagging another show for commercials. That box is pretty slow but I bet it will be finished in another 30 minutes or so. At 9pm we will watch a show that is hd. I will see then how it holds up to a pretty heavy load. At that time it will be recording 1 hd show and 1 sd show. I would think that the slave backend will be flagging commercials also.
