The mythtv performance looked like the signal was weak. Maybe it is a tuning or driver issue? I am still trying to figure it out.
I never could get my Fusion5 to show a signal strength under MythTV. When I swapped my server from MCE to MythTv, I didn't notice any difference in my ability to lock on to a signal, or signal quality. The Fusion5 performed the same. I'm now using my Fusion5's for QAM, so signal strength really isn't an issue anymore.
I would point out that if you haven't done anything with your antenna between the swap, that a video stutter could be a problem with your video driver. I had a strange problem where 2 of my HD channels would stutter badly. It turned out to be the Nvidia driver I was using. For some reason it would peg the Xorg process at 100% as soon as I tuned to those channels. I updated to a newer Nvidia driver ( don't remember the exact version number off the top of my head, but it was a 9xxx series driver) and that solved my stuttering problem.
