one thing that gets me, is that the 640x360 version is sometimes
referred to as hd when it is really the source of the file that may have been hd.

don't mind me, i'm just rambling..
mb
the reference in the filename is typically relating to the **source** ... ie
pdtv, dsr, hdtv or hr hdtv.. and while dsr, pdtv and hdtv files are usually the
same size (350mb) it's quite easy to see the difference if you compare them. hr
hdtv are usually 700mb.
