My DVR box keeps freezing and I am sick of it

[#1]

For the last 2 or so months my dvr box has started freezing for hours on end.  More recently it is becoming more frequent and worse.  Last night it froze at 9 pm and is still frozen now.  But the other box I have that is not DVR works fine.  What's the issue?

Possible bug.  Are you on 1.9 or 1.9.1.

And of course the box may be failing, often the hard drive.

I'm a technical **bleep** what is  1.9 or 1.9.1?  And the box is relatively new.  It just started doing this.  When I go through the reboot process it doesn't help.

The software/firmware they run on the boxes is collectively called IMG.  IMG 1.9 is what most of the country is on, but they are starting to roll-out 1.9.1 which includes fixes for some types of freezes.  So far in VHO 1 (California and Texas)
