Has anyone compared the different companies?

[popeddie]

In Los Angeles, there seem to be: AT&T, FiOS, Time Warner, Direct TV and Dish

For TV use, has anyone compared the features and channel line up?

I would like a DVR and like the AT&T option of recording up to 4 shows at once and watching them in any room. Are they the only guys who do that?

Is there anyone who has put together a simple list comparing the channels (I can't find a full list the net)

Thanks for your thoughts!
