Sorry about the cookie problem. It's because of the dns change -- the url of the forums changed from uechi-ryu-temp.ath.cx to uechi-ryu.com. I wrote a script that will redirect people to the correct url if they're using an old one.
As for the videos problem... the videos aren't on this server (as far as I know). You're talking about ( http://abcisp.net/~gmattson/video/streaming.html
), right? That's @ abcisp.net, not at uechi-ryu.com.
This server has huge gigabit connections to main internet backbones like Time Warner, Verio, Cogent, Williams, etc. If you have cable or dsl and aren't experiencing any client-side difficulties, everything should download at a quick rate. Please let me know if this isn't the case -- I'll look into it.
