I have been successfully using my PBO for a few years now but recently had an issue with playback. My PBO is connected to my PC via Cat5, and when I access my selected videos I initially get a "Testing Network Speed" message followed in a few seconds by confirmation that the video is selected. I can then press play and away I go. Lately I get the Testing message but no confirmation that the video is selected. If I try to move to another video I see that infact the PBO appears locked up and it can take several minutes before I can navigate around again. I suspected a connection issue so I switched to my Patriot wireless adapter which the media player accepted and showed good strength for. Same problem after selecting the video and getting the Testing Network Speed message. No playback and PBO is hung. I then tried to update firmware (I have BC 16) to a more recent P61. Now my PBO has a completely different look but the problem remains the same. Any thoughts?
