agreed, not worth it.
this app doesn't provide live tv streams, but it sure does provide most every show you could think of.
-TV Shows Stream-
it's $8 in the market, and has a free Lite version with about 9 shows (including Simpsons/Lost/Heroes/Southpark, etc). open the app, check out the 'see premium shows' or whatever to get the list of all available shows in the $8 version. it's insane. i love it (simpsons, archer, venture brothers, pushing daisies, arrested development, IT Crowd, metalocalypse, etc). every season/episode.
EDIT:
it's only $5.99 until April 15th
