Sorry I wasn't on the IRC when you connected.
Your videos are excellent, but they're missing the mandatory signature that should appear in the first few seconds. You can see a sample on (almost) every longplay on the site.
The procedure is described in the following tutorial
If you need additional information, you can ask any of the admins on the IRC channel, namely Geekmeister, T-0815, ScHlAuChi (our very own video wizard), RickyC and myself.
Hope to hear from you soon ;-)
