I've got the same NUC and two of the same tuners. I'll need to check what's the situation currently, but indeed on beta 3 I did not get any pixelation. The issue I was seeing was that if I just watch the TV or record the TV, there's no problems. But if I open EPG, the menus or sometimes even the info overlay, I start to get continuity counter errors in Tvheadend (enable debugging to see these in the logs). It would seem to me that whatever menus I display in XBMC over the live TV picture should not impact Tvheadend! I'll need to check the situation with beta 7, haven't had too much time lately.

However, I got another issue with 2 of these tuners. Basically the xHCI host dies if I try to use 2 of these tuners simultaneously. The same happens on an Ubuntu linux, so this is not an OpenELEC or XBMC issue. I reported this as an Ubuntu bug, I hope those guys have means to further look into this or ask me for further debug printouts (https://bugs.launchpad.net/ubuntu/+sourc...ug/1313279 ). I have that Ubuntu on a USB hard disk. Funny thing is, if I take the hard disk and the tuners, connect them to another PC I have (Ivy Bridge Core i5) I can use both of them without any issues. So either there's something wrong with the NUC or then there's an issue in the kernel drivers somewhere, I reckon. Do you have multiple tuners?

Thanks for the reply trsqr, would be really interesting to hear about any further testing you are able to do, since yours is the only report I can find of live TV working on the Gotham betas. There's a whole load of reports over on the Openelec forum

which seem to be describing the same problems as I am experiencing.

As for the multiple tuners, I am afraid I only have one so cannot test, but I wonder if it's a USB 2/3 issue? I assume they're on the USB3 bus on the NUC, and USB2 on the Ivy Bridge? Could be a clue ....
