Hi Radar,
Thanks for your reply. The file was transferred to a friends laptop running media player 9 and winXPhome. It still produced the 'Error loading codec' message but then played OK rather than crashed.
We tried matching all the codecs between the machines via a data transfer cable but to no avail.
Since then other MPEG's have played OK so perhaps you are right to suspect the camera rather than the 'puter.
Would it be worth installing the driver and any available software for this camera on our computer? or will it not make any difference.
Thanks again.
