Hello Ken,
Did you try de Java Media player in Solaris to play mpeg movies?
I found the video performance impressive.
As I remember correctly the Java Media Player is the only player which
uses the libutmedia and thus might benefit most of the new features.
See for more detail earlier posts:

This is incorrect. We have essentially done nothing to the code/data
path used by libutmedia, which was already pretty optimal.
What we've done (among many other things) is to add the ability to
leverage the same YUV protocol through a standard interface - the Xvideo
extension. We've also created a direct path for YUV protocol from
Windows Media players to the Sun Ray client.
So, jmplay still should provide the fastest path for video from
Solaris. realplay and other media players that utilize Xvideo should
achieve better performance, although it's probably still not as good as
libutmedia since the X server is involved in the data path.
That said, there's a pretty significant change request (CR) filed
against JMF on x86 architectures:
6561243: Video appears blue on Solaris x86 when playing MPEG files on a
Sun Ray
This is a color-mask handling problem in the Java Media Framework that
results in red-blue reversal for X drivers that use atypical color masks
(Sun Ray uses BGR instead of RGB, and JMF doesn't handle that properly).
If you have a support contract and jmplay on x86 is important to you
consider calling Sun support and asking for an escalation of that CR.
Right now I believe the perception is that the issue is not important to
people since the CR hasn't engendered much interest via the support
channel (customer call records, escalations, etc).
