Apologies if this is specific to JW Media Player 4 (which I've installed for SWF Tools).

There is supposed to be a 'config' flashvar that loads an XML file, although the JW Media Player 4 flashvar docs do not say what form it should take.

I have a local Drupal installation in 

/drupal<code> under my web root.

I've tried all of the following:
<code>
config="http://localhost/drupal/sites/default/config_jwplayer.xml"
config="/drupal/sites/default/config_jwplayer.xml"
config="drupal/sites/default/config_jwplayer.xml"
config="/sites/default/config_jwplayer.xml"
config="sites/default/config_jwplayer.xml"
config=http://localhost/drupal/sites/default/config_jwplayer.xml
config=/drupal/sites/default/config_jwplayer.xml
config=drupal/sites/default/config_jwplayer.xml
config=/sites/default/config_jwplayer.xml
config=sites/default/config_jwplayer.xml

None load: the XML config_jwplayer.xml is:

<config>
<repeat>always</repeat>
<width>267</width>
<height>200</height>
</config>

It works fine if I pass arguments query-like:

repeat=always&width=267&height=200

Has anybody got this to work via FlashField or otherwise ?
