They say a picture is worth a thousand words, however I think a video is worth far more....
Personally, I liked the addition on the main page. It gives some prespective to why this site is promoting a particular series for a given month. Many people get turned on or off by the opening credits of a show, so being able to display it openly gives the prespective viewer/downloader a chance to see some of what they might see.
I run cable internet, and loaded the main page while on an MMORPG and they page had no difficulties loading. The one concern I would raise, and its only in the interest of those who think the page either loads too slow, there's too much content, or have fears the video/flash load will bog down your loading time coming here would be to suggest a gateway page when you load the URL of fansub.tv. Give the web surfer the choice of loading the standard page displaying a random image of the recommended series of the month or loading the flash page containing the video clip.
To be fair to the site, I've had longer loading times going to IGN then loading the main page here, so as a frenquent visitor to this place I have no problems with it. Its a nice addition IMO.
On a side note, everytime I try to load the link from the OP I keep getting nothing. Did you take the page down by chance?
