I’m looking for an HDMI-capable TV Tuner card (that preferably works with linux). Thanks!
My suggestions is to do an online product search and including Linux Compatible in the search like below:
Linux Compatable TV Tuner Cards - Google Search
Normally, unless you have found a combination TV card Video card (ATI used to have such), the HDMI output will come from your video card, not the tuner card. You can use a DVI to HDM cable adapter. Next, you need to know how the audio will be sent. HDMI can contain audio, but if it comes from the video card, no audio may be present. Last, if you are using built-in audio or an add in sound card, the audio will not be sent through the video card. You may find such a thing, but it will not be that common. I will say that normally, I send my video to the TV directly from the video card using a DVI to HDMI connector and I send the audio directly to my receiver using a optical cable, so the two are never connected together. I have a TV card that can pick up digital TV over the air, but I never got it to work in Linux and since it does work with Windows, I did not try to purchase a new one. I would look to see if there is a cable card solution you could buy as it will provide the same service you are paying for from cable if you use cable.
Thank You,
Thanks, that’s VERY helpful!
I had no idea the HDMI could come from the video card instead.
If I’m hooking from the cable box to the computer, can I send the HDMI straight to the video card? Do I not need a tv tuner?
Hdmi in cards are very expensive over $1k last I checked. Use firewire.

So, if you have a cable box, their is no need to send it through the computer to the TV. Think about it. If you want to watch live TV, do not run it through your PC. So then, what are you using the computer for really? A PVR (Personnel Video Recorder) is the most common answer. You can record anything you want to compatible file formats that can be use on any PC or even DVD player. What I do is use a HDMI switch box. I found a four input model for under $50 US and 3 input model for under $30 US and all with little input switcher remote controls. Trust me, if you want to watch live TV, use the cable box through an HDMI switcher to the TV direcly.
You can use the cable box to feed both the TV and computer though not every possible connection setup might exist, depending on the box. That is why a cable card setup would be a better, but more expensive choice. I ended up with a dual TV tuner, one for analog TV and one for ATSC outside Digital TV. I put up a digital antenna and can get HD recordings for all local programming and analog from cable for everything else. It is a KWorld Hybrid tuner and it was very cheap and works great, with Windows, but not Linux. It is my PVR and it saves me $16 a month verses a cable company supplied HD recorder. I use the Windows program Beyond TV which is a great bargin. It worked fine with XP and it works fine with Win7. But again, it was not a Linux solution.
Thank You,
Two questions:
- Can you post a link to where I can get this?
- Does this enable sending it to both at the same time? Or is it only one at a time?
This is what I want to do (well, I think it’d actually feed the computer which would then feed the TV so I could use MythTV to either watch live tv or view my recorded stuff). I want to set up MythTV, but I’d like to be able to do it with HD channels as well as non-HD. MythTV, Open Source DVR
Here is the HDMI switcher that I use:
IOGEAR GHDMIS4 Video/audio switch - 4 ports
As for how to connect a cable box to a TV tuner, the only way really is using a video capture card with monitor ability. Otherwise, the only other way is a cable card setup or doing the way I do. I got a hybrid tuner card as stated before and connect the Digital to an outside antenna and the analog connection to Time Warner Cable. It is hard to say how long the latter connection will continue to work. If your cable box offers RF output at channel 3 or 4 as in the old days, you could connect that to your PC Tuner card as well. At some point, you will need a cable card or switch to just ATSC over the air digital broadcasts entirely.
Thank You,
Why can’t I connect it the same way I do the TV? Or is that because then the MythTV can’t control the cable box?

For the PVR function to work, you need to be able to select the channel you want to record from your computer. If you can’t select the channel from your PC, then it will not be of much value to you no matter what TV program software you are running on your PC.
Thank You,
Ah, gotcha. One last question on your setup: are you able to record all the HD channels? Or only the network ones?

I can record all over the air HD channels which is about nine where I live. To record such from cable, you need a Tuner able to receive Clear QAM in HD over the cable. This is simply unencrypted HD content. But, such content here is no different from what you can get over the air with a Digital Antenna and a ATSC digital tuner card. So, what would it take to record HD content other than local channels? A working cable card and cable card adapter. This is the only solution that provides the same content as a cable box. However, such a tuner can be expensive and hard to get and requires you “rent” the cable card from your local cable company. There is lots of other HD content out there, but for me, I use the over the air free stuff or my analog cable choices for no added monthly charge. If I really wanted to record some other content, I can use my single cable box to do so, but my wife seems to keep it busy most of the time.lol!
Thank You,
Why can’t I do this?
- connect the computer to the cable box the same as I connect the TV to the cable box (via HDMI)
- Add a second connection for PVR that enables the MythTV to change channels, etc
Wouldn’t that give me all HD channels?

Well can your cable box channel be selected in some way by your computer by some software running on that computer through some sort of physical connection? Do you have an input on your computer that allows you to view an HDMI output from a cable box that one could record (capture)? Keep in mind I have in no way seen every cable box out there, but there are certain issues to overcome when trying to use a cable box connected to a computer with these two being the biggest problem. And generally, running a cable box output through a computer to a monitor (with a compatible direct input such as HDMI) does not add any value to the picture being viewed. That just means again a computer is mainly a PVR device with regards to TV.
Thank You,
Thank You,
Cable companies by law must have the FireWire port enabled. Any unencrypted channel can be recorded from the FireWire port. This for the most part is a cost effective way to record HD TV other then over the air. The cable box can also be controlled via the firewire, switching channels etc. Last time I tried this it was mostly command line, there may be better alteritives now.

but do they enforce that in all EU countries, or just yours?
