Hi.
Tested on vlc 2.0.6 and 2.0.7 on windows 7.
I have minidlna server, few videofiles in few sizes (xvid video, ac3 sound): 745mb, 1,4 gb, 2,1 gb.
Android devices (bubbleupnp and mx player), hardware players (wdtv live), windows media player can play all sizes of video file.
But VLC can play any of them except more then 2gb.
It looks like bug, but maybe it's somewhere option for it?
