Sling does this. For Dish Networks customers, it's free and built-in to some box models and an easy plug in for others. The feature, Dish Anywhere, allows you to watch all the content available on the box (live, DVR'd programs, or on demand) from any network connected PC. There are apps for Android and IOS to watch from any Tablet or smartphone. There's a Kindle Fire app too.

I have it and use it all the time. Family members out of town, and one in another country, use it too. We removed a TV from the kitchen because we can use a large screen laptop that can be placed anywhere and oriented in any direction. We also use it outside in the shaded part of our patio (screens are hard to see if in direct sunlight). Within the house and with a fast enough internet uplink speed for viewing from elsewhere (which I have), the quality is HD and the same as a TV directly connected.

Steve - the tuner card died maybe 3 years ago and it is at least 10 yrs old so I will buy a new one for my new computer before I try to mess with that one.

Elmer - the Dish network looks pretty cool. thanks

Never mind. Turns out my cable company streams live tv on their web site. Free and no gizmos to buy. All set. Thanks

While the Cable company streaming video is good, it doesn't allow you to record onto the PC or laptop. In our area Spectrum cable has gone to full digital so even a TV tuner card won't work with cable service. My antenna still works to my TV tuner card, so I can record OTA if I want to. Some of the newer TV tuner cards use a cable card that will allow cable reception to your PC and allow recording.

Mike, you would need to use the output from your cable box to go to your tuner card, or use a cable card.

Steve - I won't rent another cable box - they already want too many $$$ as it is. I use a ROKU stick on other TV; you can get a ROKU with a composite out, don't know if HD would be available that way, also don't know how you could select an individual program for recording.

Roku has an HD out. It would work the same way as the cable box. You use the cable box/roku or other to decrypt or authenticate, and the TV or hd out would go to your capture card and essentially serve as the TV or monitor. You'd have to watch the program in real time on the source device unfortunately. All depends on the purpose.

HDHomerunPrime from Silicon Dust might be an answer for you. I've used the three-tuner model for several years with Windows Media Center running on Windows 7. Windows 10 is a problem since Media Center isn't supported but the Homerun works fine with Kodi and Silicon Dust also makes DVR software (which I don't use). This solution has worked well and means no cable boxes or multiple outlet charges. Perhaps you've already solved your problem; if not, hope this helps.
