The more software the more potential for bugs. I've had to run a software update on my Sony Bravia because there was a software bug that after 1200 hours of use it wouldn't get out of sleep mode. In the end they sent me a USB drive with a firmware update and when I tell people what happened I explain it as "I had to do a Windows Update for my TV". Funny enough, people understand perfectly:).
My Dish Network DVR is hooked up to my AT&T DSL @ 3 MB/s. It's how I get my programming guide updates. I also have a Roku for Netflix streaming. I'm a big fan of both boxes.
But it'd be nice if I could just use my Dish Network DVR for my Netflix streaming. At least that way we could get rid of at least 1 remote on our coffee table.
