A slightly better solution to avoid the ground loop audio issue, is to get rid of the analog audio cables altogether, and use an optical audio cable from the TV to the back of the iRV-66.
Feeding the cable through along the path taken by the other cables was a bit of a pain (I used some coax-ax, which is much stiffer than an optical cable, to feed through, then attached one end of the optical cable to the co-ax and pulled it through).
The added benefit is that if the TV station broadcasts surround sound, you now get real 5.1, rather than just stereo/prologic from suitable TV broadcasts (mostly movies)
