every version of 3.x.x has been a problem for me, I would really like the added features but movies stutter and many will play for a short while and terminate with a stream interrupted error. I just installed 3.4.2 and the same thing all over again, the only fix is to completely remove it and reinstall 2.7.1 (this version is the last stable one for my application) I am using this on a windows 2003R2 x64 server streaming to direct-tv boxes on my home network. everything is CAT5 gigabit connected. please help me.
