give people too many choices and they can't make up their mind...
I noticed that with a large library people can't choose from it what to watch, the sheep that are used to tv need a media player that basically has a comedy central channel, a cartoon network channel, discovery channel, etc, and just randomly pick a show playing the first episode you haven't watched, then if you're not into it just hit next show for it to change to something else that fits the channel.
I haven't played around with any of these players to see if any of them can simulate tv channels well since my friends need that kind of structure more than me. They'd even benefit from commercials to be thrown back in there so they know when to get food, piss, smoke etc...
