ah yes I have heard these rumors, but I also hear they have viruses a lot. I think I might just have to borrow a friends tv when needed.
I've heard you can get a virus scanner for your PC, if you can conceive of such a thing.
Any standard anti-virus software suite will include scanning all downloads for viruses.
If you do opt to borrow a TV and plan to watch by antenna, make sure it's a late-model set with a built-in digital receiver. Anything using old analog receivers won't get more than static without a converter box attached - the new digital broadcasting rules means that all the channel frequencies were changed as well as converted to a digital signal. Anything HD and built in the past few years probably fits the bill. Don't even bother looking for a standard-definition TV - as far as the stores and broadcasters are concerned, they no longer exist.
I hear there's some pretty interesting stuff on DTV broadcasts. The FCC alloted each channel with a certain amount of bandwidth capacity - if you were a broadcaster, you could use it to broadcast a single feed at full 1080p resolution (which few if any broadcasters do) or you could actually break up the channel into as many as SIX sub-channels. I saw that WPIX-11 in New York has a sub-channel that broadcasts nothing but old Sixties TV shows. Sub-channels can be automatically detected by your digital tuner and will appear as "channel 11.1" or 11.2, 11.3 etc. A lot of channels are using at least some of their capacity to broadcast at least one sub-channel, if for nothing else but weather and traffic updates.
