I bought a Windows PC to run my TV before Android TV was a thing. It came with a remote, Bluray software, and a TV tuner.
The whole thing just felt half-assed. I'm not going back. MS really missed an opportunity, because if it wasn't for quality issues, it would have been halfway decent.
Prior to that I used a mac mini with a TV tuner. The TV tuner software was horrible; the UI for programming the DVR was like writing SQL queries. I have a degree in computer science so I could understand it, but there was no way I'd try to explain that to someone who wasn't interested in databases.
