I tried for a long time to use the Ceton InifiniTV4 with MC and found that it had way too much pixelization and picture breakup. It worked fine with WMC but in JR MC it acted just like it would if the signal was low. I gave up using JR for cable TV because of the issue. I found much too my surprise that the HD Homerun Prime worked fine in JR MC without picture breakup. The weird thing is that the Silicondust tuner is slightly more prone to get pixelization in WMC than the Ceton. Both basically work fine WMC but only the Silicondust tuner works on my cable drop with JRiver. Of course MC does not release the HD Prime Tuners properly which is annoying but not a complete showstopper like the playback issue with the Ceton and MC.
