I tend to agree; but in the mean time, I found out that if I type a keyword in the "Video" box, and leave the "Type" box blank, I get the results I want and nothing else. For instance, I just typed in "lacuna coil" (w/o the "), and within 1 minite, I got 13 results...all Lacuna Coil.

I do think searches should be based on the filename, not the ID3 tag or metadata.
