I would assume these bugs would be fixed by now.
You are assuming too much.
We have had Fios for a few months now and are running the latest 1.6.2 software. Bugs are fairly common:
1. Yes, we see this randomly as well.
2. Yes, we see this randomly as well.
3. We haven't seen this exact bug, but for example a few times I have seen the DVR report that it is 80% full, so I'll delete a 2 hour HD show and instead of it saying it is 75% full the number actually goes up to 83%. ???
I am at work so I don't recall how to see the software version. I thought it was under one of the Settings menu choices though.
