Been reading the forums for quite some time now and have seen this mentioned before. Watching CSI this evening about 15 minutes after it started recording and my HR20 rebooted. Just like a power outage which we did not have, it is on battery backup anyway. It went through the whole routine and even resumed my recording of CSI. I now know that the guide info is not lost after a restart. I have had good luck with the machine, the normal HR20 quirks but quite reliable otherwise. What would cause this? I have had DVR's for years and never had this happen before. Seems to be working properly now. Is this a known issue or do I have other problems? Thank's in advance.
