TV Tuner

No idea. Get a bump instead.

Maybe use IPTV instead. if channels are available, or do you want convert analog videos to digital?

Bump

Do you mean a tv card? Satellite (DVB-S2), cable (DVB-C) or terrestrial (DVB-T/T2/ATSC)? Or a combination of those?

I can help here since I was looking for the same thing these days and had to read up on all aspects of video transmission before making a choice. Also, I was not on the largest budget so I had to choose wisely.

I was looking for something which would work on a laptop as well (not an internal card) so a usb tuner. capture works anyway with any tuner and picture in picture or dual station capture was optional.

For standard cable, what you will need is a tv tuner with analog receiving capabilities. Should your cable be sending digital and HD channels, you will need a tuner which can receive the DVB-C standard. For digital air transmissions, you will need dvb-t or dvb-t2. Its a hassle to figure out what you have. I needed analog as well as dvb-c and I found a great hybrid tuner for a very decent price on the website aliexpress. It also has free shipping worldwide and costs only 25usd. Chances are this will be ok for you as well. Link is below. Good luck and hope it'll be what you need.

I had one as PCI-express x1.
Now I have an pluggable Hybrid PCTV.

So my recomendation is one: Buy pluggable. You can use it with laptop too later...

I have an old K-media PC-TV PCI-E card in my computer as I don't have a real TV. The software it came with doesn't support newer operating systems but if you can pick one up cheap on ebay or whatever I'd say go for it - it works great for receiving terrestrial digital TV with VLC (freeware) on both Windows 7 and linux and also has physical inputs for my obsolete consoles and VHS player so I can play them in a window on my desktop.

I skimmed the above posts and it sounds like you're trying to pick up OTA broadcasts. I'd recommend an HD HomeRun from Silicon Dust. It's external and works over your network, so multiple computers can use it. I don't have personal experience with one, but they come highly recommended. I don't have a TV card in my desktop, but I have a dedicated PC for recording TV. I use a Hauppauge HVR-2250 dual TV tuner. It does OTA ATSC, Clear QAM cable and regular old cable.

I have no clue as to what a TV Tuner is, (guessing it has something to do with watching TV on your computer?) so have a bump :)
