Recommendation on an HDTV tuner for Win 8 x64?

I use an AVerMedia Duet (white box version) for OTA and it works great with Win7 WMC. Supposedly also works with clear QAM. The company's website states it's discontinued but they told me they are temporarily out of stock. So who knows. Anyway I picked up a second one for $50 from ebay.

In case you're not aware, there is also the HD Homerun Prime, which uses a network connection. It's a three tuner cablecard device. There's an older HDHR two tuner device which is not cablecard, but will do clearQAM and OTA.

Are you looking for an ATSC tuner for OTA reception or a cablecard tuner for digital cable? The Hauppauge WinTV-HVR-1600 is a single ATSC tuner for a PCI slot. Aside from the SiliconDust HDHomeRun that was mentioned, there are lots of USB tuners for both ATSC and digital cable. Here's my favorite source for tuner information:

FYI, SiliconDust makes two versions of the HDHomeRun. The Dual is a 2-tuner ATSC networked tuner and the Prime is a 3-tuner networked cablecard tuner.

The SiliconDust HDHomeRun will probably be your best bet, assuming you have a home network set up. They just came out with drivers for Windows 8 so it should work fine with your system. I don;t know of any PCI cards that work with Windows 8, although there may be a few off-brand models out there. I see an MSI PCI ATSC tuner on sale at Newegg quite often, but the reviews aren't anything spectacular. As long as you can get a strong signal via an antenna I would think most internal tuners will do the job. Otherwise, get yourself a USB tuner. The website I linked you to has links for sources in each of the individual tuner reviews. I believe the AverTV Volar Max USB tuner is available new for about $50.

The Hauppauge 1600 you mentioned states it is Windows 8/7/Vista/XP compatible though I won't get to try it on Windows 8 until around Christmas. I did notice a "new" 2.6c driver released 11/1. I've had my 1600s since before they were qam capable ... its only been the last few months where the analog (cable) tuners have gone out (yes I still get analog cable just not on those tuners) and have resorted to using a vcr to tune those analog channels.

If you're dead set on using Win 8 you're not going to find too many PCI tuners with compatible drivers. I've seen a few PCI boards still in production, but they're mostly off-brand boards that tend to get spotty recommendations at best. If you can use Windows 7 then you have a lot more choices. The VBox DAT150 is an excellent PCI ATSC tuner that is no longer in production. However, you can get Win 7 drivers for both x86 and x64 systems by contacting their customer support. These tuners show up on ebay every so often and you can probably get one for less than $25.

Newegg has MSI tuner that is in PCI format, but it is a single TV tuner.

Yes, that's the one he's referring to. Reviews are pretty sketchy on that tuner, but I see it go on sale quite often.

FYI, all PCI tuner cards will only have one integrated tuner. You'd need to go with a PCI-e card for dual tuners.

Here's a good USB tuner you might also want to consider:
