Yeah, watchin it too, and had the same issue with the last episode. Show's still hit or miss with me, but I thoroughly enjoy it when it hits.
Comcast is only giving me FXX in standard def though, so I've been waiting to watch it each week now on On Demand because they give the HD option there. Gotta love Comcast's consistency there. I wouldn't mind watching it in standard def, except for the aspect ratio issue. I end up having to zoom in, but that just lowers the video quality even more, so I wait to watch it on HD.
Considering they just brought G4 back with no new programming instead of having the new Esquire take that channel over (It's now taking over Style instead), they could just put FXX HD there. There's also an unused number next to the regular FX HD channel in my area. They really should just use that.
