This is a YouTube search/player application.

Changes:

Fix – “Failed to get security cookie” message, this was caused by YouTube changes. I have now entirely changed the way this bit works so that it is more like the flash player and should be a bit more resiliant to changes.
Fix – May work on Pocket PC 2003 devices again, please test.
