[Xperia Play Android Development] Spizzy01:
Ok... So far everything except for the YouTube issue is fixed.

I'm unsure about the Game Guardian issue as I cannot find the application on the Play Store, however there are no issues with SuperUser so there shouldn't be any issues as to why it cannot be granted such access.

As for the YouTube issue, I'm currently unsure as to the reasons behind the issue. The errors seem to be coming from a mix between the ROM and the Kernel which makes no sense at all.. Although I will change the Kernel and test again, just in case.

The logcat for the YouTube issue is as follows:

I have a few things I intend to check before doing this though - Since a large amount of standard libs have been removed from the ROM there is a small change a required lib for YouTube has been removed. Although so far I can't find which, as I've checked 90% of the ones that have been removed and none are required for Video Decoding or YouTube.

Strangely enough the Logcat does state the decoding of 720P video, so I'll try a 720P Kernel as well. Just in case...

Edit: If anyone has v1.0.0 installed, could you please test YouTube functionality and report back? Thanks.
