The first thing I thought was that it would be such a bonus if you had a .tv domain. It would suit your site's goal to a tee! Ah well, take what you can get. To the site. Not bad, good colors and relatively good navigation. I would consider renaming that Recent Topics portion to Hot Topics just to throw off a little flare and allure. Then where you have the 2 links (more...; Visit Forums), first of all, take off that semi-colon, it looks unprofessional. Second, rename "more" to "More Hot Topics" and leave a little space after that, then put "or Visit The Forums".
On that same index page, align the content in the Visitors box to the left, to keep it consistent with the rest of the page. The News link leads to absolutely nowhere. Do I need to be logged in to see something or is it just a blank white page? Either make it a dead link (<a href="#">) or dont put it at all, its quite unprofessional. Another problem with the News link, if I click on the News link at the top (and not the News link you have in the boxed menu) I probably would'nt have noticed the 2 new options you have for that portion (Submit News and Archive). Not good navigation techniques.
The Newest Members box should be changed to the Newest Member as it only shows the latest member who joined. Thats just my anal'ness talking though, not a mandatory change. I'm not sure how long the images in the Fun Games portion would take a 56K'er to load, but you sure include a lof of image links to a lot of games. Are all the link necessary? Does it even relate to your site? The forum itself looks good, I like the rollover effects it provides, very cool.
I think in general you have a good thing going. I'd work on adding a little more color or images to offset all of the white. But you've done a good job with the site.
