Seeking the video can take ages, audio (playing mp3 with winamp from the cifs share) stops from time to time and also the video playback lags and pauses from time to time. The videos work just fine when I play them from my local computer, or stream them from another windows computer via CIFS.

What does local disk performance look like?  Try bonnie++
(http://will.incorrige.us/solaris-packages/CSEEbonnie++.pkg.gz or
build it yourself, it's straightforward).  Also, what ethernet card is
this?  What does "dladm show-dev" report?  How does copying a large
file behave?  Do you get bursty transfers of a higher rate, or a
steady 50 megabits (look at Windows Task Manager's various tabs)?
