Ok after quite a while, here is the update.. It should work 100% again, and plus it should put a little stress on your server. As usual you can preview it over at http://ytexp.zeryl.net/ or you can download it http://ytexp.zeryl.net/download.php
Please note that the blocking certain YouTube ID’s will be priority from now on and will come soon!

After a long time of college work, I have finally been able to update the YouTube proxy. You can now download version 1.2.1 which will fix an error which was created after YouTube changed the way it delivers videos slightly.
I am truly sorry for the long time that I was away, but as I mentioned before, college does require a lot of time, and especially since I am going to university in September, I had to make sure that I got top grades.
Same with the “more posts”, it will come, I don’t know when, but it will!
Again sorry for the long wait.
I have decided to post more often on here and not just updates for the scripts! You will read my opinions, my ideas and much more 
starting tomorrow with an idea i have been stuck with for a while now! Which i will ask you about whether you like the idea or not and whether i should try to make it reality!
Not anymore, I just recently realised that you can infact bypass the YouTube country block list. Any video that is available in the US (where zeryl.net is currently hosted) will be available through this YouTube Proxy, even if it blocked in other countries.

Google has been busy, the old script didn’t allow downloading of the videos anymore, that is fixed now though, plus HD option has been added for both streaming and downloading. You can catch version 1.2.0 over at http://www.ytexp.zeryl.net/index.php.
Please note, if you are upgrading an old version, make sure that you delete all files except config.php first and then upload the new version, skipping install.php and config.php.
Hosh
After a very long down time, we are back online. Unfortunately we had to reset everything due to technical problems, but we will be back up and running. Since it has been a while, I am not sure if the scripts are still relevant, but I will have a look at them as soon as possible (which might be a few weeks since I’m very busy with my studies)
