YOUTUBE ISSUES any real answers??

Does anyone know the real problem with the youtube issues on the 4.5 OS? I have read so many different possablities and different alternatives to fix the issue but it seems like me the problem still exists. Some videos play and others won't. That seems to be the common thread to everyone's problem. I wish BB or YOUTUBE would address this issue, Going to different sites to get to youtube eliminates many videos not to mention a pain in the ****. So if anyone has the answer, I'm willing to pay for it.

Thanks
