Whole Home DVR issues

I have two Whole Home DVR's.  Issues are not a show stopper just ANNOYING.  Here are my complaints:

1) No Caller ID showing up on the TV.  I have reported this and all the reboots in the world can't fix it on either TV.  I got exhausted and said never mind.  I don't want to have to wait on a service call either.

2) The pause only stays until the next show starts.  For example I pause a show at 5:45pm and the show changes to a new show at 6:00pm.  At exactly 6:00pm my pause stops and I can not rewind.  It's like I turned the channel which makes pause useless.

3) Two of the local HD channels contantly tile and it's only ABC and NBC.  CBS is fine.  Nothing worse than watching ABC and NBC without HD.

4) This has been with all DVR's I've ever had.  The time is off either on Cox or the channel I'm watching.  I know you can change your recording to add and extra minute to the end so you don't miss the end of the show but that causes you to not be able to record other programs that may start at the beginning of the extra minute I had to add.

5) The cost.........I guess for the amount of money I pay per month to Cox ($243.01 last month) and that's having everything, I've earned the right to complain.

PS. With all the service calls over 10 years....It's not low signal because nothing has ever fixed the tiling.  At least its down to just 2 channels now but their both HD :(
