Since updating to 3.3.4.0 firstly when playing video sudden stop with "No Device connected" although it had been until this point.
Following this buffering problems - never any with previous version. From other thread advice re-download of 3.3.4.0 and reinstall without prior uninstall : clicked for Repair. Still the same problem with buffering. Also after looking at other threads am providing the following info.:-

I must emphasize no problems with previous version with videos with same set up.
I'm pretty new to forums and hope that I have posted correctly?
