When I hooked up the new cable box HD/DVR i got a hum which is heard.When i had the other plain DVR hooked up there wasn't a hum, which was hooked up with RCA cable.This is on a Vizio E420VO 42"...

It might be abe to be fixed. It sounds like a ground side problem, so you should take it apart and see if the rca jack is well soldered and not cracked on the wire or circuit board, depending on their system.
Otherwise, the unit could be having another issue and with noise in the power supply, and will have to be replaced.
Have the cable box replaced, would be the easiest solution. I think the TV is fine, but if it ends up needing service, you can often find mobile tv repairment that will come service it at your home, saving you the hassle of taking it somewhere.
Good luck, and hope this helps.
