I'm having random issues when playing back a file stored on my server (Windows XP). I have installed the SMB/CIF package and the server is connected to the Humax via a Powerline Adapter. In most cases (99%) the video plays ok, howver on occassions the video constantly stops. I have rebooted server, router, humax and powerline adapters though the problem continues. However I could successful play the video the next day with no issues, so its not the video file. I have switched off all but the server, router and humax to determine if another n/w device is causing the problem but it still continued. Any ideas?
