I had a couple of issues which caused tearing using ION Zotac front end.
The composite-line fixed the worst of it, then tuning the VDPAU and
Resolution settings helped imrpove the image quality and remove tearing
which was happening due to screen-size mismatch to desktop.
See my post here, it will lead you to mythtv thread where this topic was
commented on by other mythtv-ers.
There are log files too which may help you troubleshoot whether you have the
same problem(s) or not. I updated a couple of mythtv wiki pages on the
subject of tearing too with references to the the composite-fix.
