Problem with WMS not playing content after upgrade to 1.09.1

[ironman]

I did upgrade to 1.09.1 few weeks ago and since then strange problem appeared.
When WMS is running for some time (>24hrs or so) it looks like streaming function stops performing well.
I can get to my movies directory on my TV, I can see icons for movie files, but when I try to play something it pauses immediatelly at black screen.
Complete cold restart of application solves the problem for some time ('Restart' function from within WMS doesn't help here).
Any ideas what can cause it?
TV is Sony 32EX500, but all worked well 'til upgrade to 1.09.1...
