Right now if you use the syntax documented on this page: http://docs.moodle.org/en/Multimedia_plugins
for controlling the size of the player for flv or swf or other media players, like so:

somepath.swf?d=640x480

It will not work if you use a larger size like this:

somepath.swf?d=1024x768

because the PHP code only accepts up to 3 digits.

I am using bigger video files to show screencasts, where you need a bigger size and resolution so the video is more readable.

To fix this, in moodle/filter/mediaplugin/filter.php, there are lines that start like this:

$search = '/<a.*?href="([^<]+\.flv)(?d=([\d]

%?))?" and so on

Change each instance of this:

[\d]

to this:

[\d]

or just use a + for repeated digits of any length.
