I'm building a S40 web app that links to videos to be downloaded and played (using mwl.loadURL).

The files download, but cannot be played, giving the following error:

"file format not supported"

The format is 3gp.

The videos could be played in 1.4.0 and earlier (Beta).
The files play when downloaded through Opera mini.

When viewing the file details, type is "unknown", but when downloaded via opera mini, type is listed as "3gp"

Any assistance would be greatly appreciated
