Last night I removed XBMC and reinstalled it. I didnt run XBMCHUB. I just installed one add-on. I streamed a full movie without a problem. Because of what I did, I can't try changing the audio output to see if that was the issue. But what I did after the XBMC install was to change the audio output to HDMI and 7.1 and then, towards the bottom changed the audio output device and the pass through that is normally optical to HDMI.
To see if the audio was the original issue, I will try running XBMCHUB tonight and change the audio settings and see if it plays back with no problem.
Thanks for the advice.
Assassin: I see that you build home theater PC's, so do you have any experience with the SSD drive? Am I just able to install the operating system and not any other programs on it (like XBMC, TMT5, Media Browser, etc.)? Could those other programs be installed in other drives and not in the SSD drive? And would those programs work correctly? I am trying not to install a lot onto the SSD.
