That sounds more like interlacing than tearing. Tearing should never
occur if you have Xv support (and, assuming your NVIDIA proprietary
drivers are properly installed, you do).
For interlacing, just enable one of the deinterlacing methods in the TV
Playback section of frontend settings. I recommend trying them all and
choosing the one you like best.

Trial and (lots of) error.
