Tried again to record OTA.
First the timer did not start. THen while trying to get to the OTA channel, the 8vsb locked up AGAIN.
After reboot (has it been about 10 times now), the OTA timer started.
However, the 921 tried to let me switch to a third live sat channel despite the fact that a HD sat channel was also recording (thus OTA & sat recording at same time). Well, this really locked up the 921. It would try to let me switch channels but not actually tune to them.
Thus, yet another reboot.
I REALLY hope they upgrade the OTA tuner software soon.
