I read an interview with one of the leaders at G4. He said that their highest rated show is Cops. He said something like (paraphrasing), "we're able to bring you AOTS and Xplay, because of shows like Cops and Cheaters". G4 just wouldn't be profitable without them, unfortunately.
comcast on demand has fallen to pieces of late. none of the shit that was on it is anymore and they moved alot of shit around so you have to freakin hunt for things. not to mention alot of times they dont update the on demand sections regularly. and apparently they can take control of your tv this happened to me recently when they were doing some kind of ebs dealy. whatever they did it actually messed up something i was recording so that another channel alltogether was recorded under the other shows name.
