Any remedy for constant tuning adapter problems?

The tuning adapter has always been problematic since I got the HD TiVo but lately it seems even more so. I find myself restarting either the TiVo, the TA or both at least once a week due to channels that won't tune in. Restarting always fixes the problem but it happens far too often and it's frustrating.



In the past when I have contacted TWC about any such issues they really don't seem to know what they are talking about, and I end up wasting a lot of time on the phone.



Has anyone had any luck getting issues like this resolved for good?



Thanks
