May 11, 201412 yr So ive recently rebuilt my server and ive searched around in the forums here a bit but didn't really find a definite answer as to whether or not unraid can act as PVR or if i will need to set u a separate box to house my tuner and leave that running 24/7 as well. if i install a cable card tuner such as a 4/6 tuner centon cable card tuner will it work within an unRaid box provided i have the tvheadend plugin installed? and if that wont work any suggestions as to what will work? i would prefer to have a single server that will handle storage and tv recording and possibly live tv but not really necessary.
May 11, 201412 yr While not directly answering your question, I do this in one unraid box using a Xen virtual machine running windows 7 to which I pass through my tuner cards and a couple of yards drives which live outside the array (75gb for timeshifting and 3tb for recordings). This works really well as it allows unraid do what it's good at - managing storage, while I can experiment with different software etc in my isolated 'tvserver' vm. You need unraid 6 and suitable hardware for passthrough to do this, of course, but I think even if I was using a Linux based backend such as tv headend, I'd still set up a vm to run it on as it gives so much more flexibility and reduces the chances of hosing your unraid set up by implementing something that's somewhat edge case.

May 12, 201412 yr I have been using unRAID 6 and a mythtv vm for awhile now. Used to have a separate mythtvbackend/xbmc frontend. Then moved it to its own vm on unRAID. And now I run a single ubuntu server 14.04 vm with a separate hard drive mounted inside the vm for live and recorded tv. I have two silicondust hd homerun prime cablecard network tuners. The thing I didn't like about the ceton card was that you could only use it with one Windows machine and the extenders associated with it. Or you'd have to dedicate a tuner to a specific machine. Not sure if that's still valid or not. With mythtv and the hdhr3 I can use as many computers as I want but just limited by tuners available. I can use 100 different computers but only 12 at a time with my setup. You can tune in a couple channels per tuner with mythtv. Right now I have my unRAID server which will use about 35 watts with all array drives spun down but the myth backend serving up a couple tv channels. I have a zotac zbox id 41 in the living room running Openelec and 3 raspberry pi's running Openelec in the bedrooms.
May 12, 201412 yr The hdhr's can be activated through the cable company with info from their webui. My recent vm I followed the guide on installing ubuntu server 12.04 / 14.04 to install 14.04. I couldn't get myth to install from the options so I followed the guide to install a master backend on ubuntu server manually. I then setup xbmc on each computer using the cmyth plugin for live tv and recordings. I use the same mysql server for xbmc and mythtv and apache for mythweb. I ssh into ubuntu to run the mythbackend setup since its graphical and I don't have a desktop installed. I use schedules direct for guide data. I'm not sure how the ceton works with mythtv. There is also a plugin for xbmc for Windows media center tv.

Seems like a great low power option, lots of cores to share for vms, etc, but if I can't do passthrough, i'm not sure I'm ready to make the leap to that setup just yet.
May 21, 201412 yr No I don't think it supports vt-d just vt-x but haven't tried either. One problem I do have is that parity checks cause the tv to buffer. I did try using a ssd data.img partition and increase mythtv buffer but still stutters. I might try a pciex sata card. In hind sight I might have just bought a different 6 sata port board, xeon and sas
