HD Channels get stuck every 2 seconds (solved)

Just got my TBS5922 and having some problem on s2 HD channels.
I'm using the TBS5922 with my Zotac ZBox PC, OS Win7 32Bit, HD Channels get stuck every 2 seconds, very annoying, no problem on s1 frequencies...
Works ok with my dreambox800 ,
Can someone please advice me regard what should i change (what video decoder to use maybe ...)
I'm using ProgDVB/DreamDVB
Thanks
