The YouTube team reached out to the Community Management team here at PlayStation to relay a message to anyone who felt that the YouTube peformance on the PS3 app could be better. Here's the message from YouTube's David Dengler who supports their communications to their audience within the YouTube forums.
Thanks everyone for all the feedback on the YouTube app for PS3. We're in the process of working on a fix to address the video quality issues. This should improve your YouTube viewing experience on your PS3!

¤ Thanks for passing the message along
will not be using the youtube app. i thought it was useless and slow.
The youtube app stinks because of the limited results, and videos not pre-loading enough ahead of time even if you pause the video. Just download all of the data please....
