I have no desire to watch YouTube in my bedroom, but I have a PC hooked up to the TV in my family room (and PS3, Wii, Xbox 360, so my entertainment needs are covered out there), which I stream WWE and UFC PPVs on (usually in HD too!). I also just noticed my new DVR has a 500GB HDD, which is pretty nice, they said I can swap out the older one too. The old one is a Scientific Atlanta 8300 HDC, which apparently is pretty old school, the new one is made by Samsung, same software on it, but it boots (after a hard reset) in about 1 minute as opposed to to the 5-10 for the old one.
Also, I realized the modem/router (1 unit) sucks as a wireless router (at least with my laptop, constantly dropped the connection no matter which channel I used), so I used my old Linksys, and i get about 25Mb/sec. That's pretty good for the US, though I imagine in Europe they laugh at stuff like that.
