I have searched this forum and many others, for this problem.
and I get the same problem with every software package I have used.
When streaming videos or even having the media server running, I get random black screen flashes.
I read on the ps3 forum that the ps3 could be trying to download a new packet and missing the data, but the audio is still there just no picture.
Other than that everything works brilliantly.
and this only happens when streaming, games and blu rays work great.
Any help would be appreciated.
