1) Yes The Adobe flash player is used for viewing . 2) Please suggest whether Youtube on Linux is using UVD by design or not. 3) Since UVD is not implemented yet in driver , does the playing the HD stream with hardware accelearation enabled in You Tube window impacts the performance and buffering time.

The open driver does not support UVD at this time, and adobe flash does not use any acceleration support provided by the open driver at this time.
