update and errata - okay this is the error I get back. Looks like the xml is either being parsed incorrectly, or it is expecting something my browser just ain't sending:

This bit appears in a one row table:

?fid=&ext=.m3u Stream ?NODATA&SERIAL=%23 Play Length Type Artist Source

And then this appears further down the page:

EEEEEE FFFFFF ?fid=&ext=.m3u ?NODATA&SERIAL=%23 ?fid= ?fid=&ext=.xml

I have resent and rechecked everything connected with the xsl stuff, and hijack, but still no joy.

Unfortunately I know very little about xml so not even sure where this would point.
