I never said that the HR20 was a bad unit. All I said was that the HDTivo was a solid unit. The bugs present may or may not affect the majority of users or a single user. There are, however many known issues that directv is trying very hard to correct. It is hard to live through the growing pain of a unit like this when the wife is on your back about why lost didn't record.
If you don't need mpeg4 locals there is no reason to take a chance on the HR20 right now. He'll loose OTA, dual live buffers and the 30 second skip. The unit has potential but it needs for things to be completely worked out beofe commiting to it.
