Trouble Playing Videos from a PC SMB share

[takethecake]

I'm getting the dreaded "file no longer available" every time I try and play a video on the Pi from my MySQL server on my windows machine. I'm pretty sure I've got my syntax correct as far as using SMB shares, forward slashes/backward slashes, using IP address instead of computer name, etc. I went into the log, and I think my problem is coming from these couple lines:

ERROR: LoadSources Error loading special://masterprofile/sources.xml: Line 38, Error reading end tag.
ERROR: Error: Requested setting (audiooutput.guisoundmode) was not found. It must be case-sensitive

Any clues? Let me know if you guys need any other info
