Um... Pardon me if I'm misunderstanding, but... A TV is a monitor and a tuner (a really basic computer). The PC takes care of all the decoding and just sends a video signal to your monitor. I'm not familiar with how HDMI works, so maybe that argument has some substance behind it with HDMI, but not with CRTs, which you seem to be arguing around.
Moreover, you still hook up your computer to your CRT tv? You can't get someone to give you their old CRT monitor? I just got a ~20" CRT monitor for FREE. They're not that hard to come by.
Dude, usually I'm behind the tech curve as well, but I feel like you're trying to name drop with CRT and VHS, except you're 12 years behind. You're making yourself look outdated.
All of those things are consumer electronics. Personal Computers sometimes have non-commercial software on them by the operator's choice.
You don't change the OS on your TV or radio for a reason.
If you have a procedure with 10 parameters, you probably missed some.
