I'm one the lucky ones that got 1 of the 1st batch of HR20s back in 06 and haven't had too many issues. Until yesterday...I set to record the Olympics and when I came back home it had only recorded 29 minutes even though it was still set to the right channel so no conflicts. It wouldn't let me pause, rewind or anything, it would just make the noise it makes when you hit the wrong button but wouldn't do anything. I did a RBR and that fixed the problem but am worried that it might be the start of more issues. Is this a common issue? Anyone know what causes it?
