It's a whole channel dedicated to videogames... I don't watch it a lot (only catch re-runs) but it's made by gamers, so they have some pretty cool stuff. This what I've seen so far:
- Roundtable interviews of game designers.
- "Behind the scenes" spotlight interviews of game development houses.
- Fighting game tournaments.
Then at night they have several anime shows (currently, Rahxephon at 9pm).
Maybe not the most pro thing ever, but they take themselves seriously and it's the most mature (as in, established and working - some antics the announcers pull can be moronic) gaming show I can think of.
