Problem description:
I followed Fred's "RE: [Part 3] Download torrent & newsserver packages" and have a downloader rigged. I followed his instructions and moved the download folders to an external hhd attached to the pi.

Weird thing is: once downloaded, the xbian will play the files, but with no audio. I've tried it with a few.

Extra weird: if I look at the files on my PC across the room over the network, they play correctly.

Also: other video files on the same hdd play just fine.

Any ideas?

[PS: where is xbian hiding the configurations for my HDD? When I type sudo net config list it has parameters detailed for both my hard drives (set to share vie gui), but when I open the samba conf files, they are nowhere to be seen?]
