I was recording "24" last night on the local Fox affliate (SAT feed--not OTA). We were watching the show about 30 minutes behind real time, and after 15 minutes, the screen froze, we saw a gray screen with a small "x" in the middle and then finally the unit rebooted. This looked suspiciously like a Linux screen, so I am supposing that the computer crashed and rebooted. The good news is that after the 6 minute reboot (can't believe it takes that long!), "24" began recording again. We missed 6 minutes of the show, however. I was also recording "Frazier" on my NBC OTA HD affliate at the same time, and it did not resume recording when the unit powered back up.
