it works fine with both pc's

both have windows xp...... well, i think the codec might not work with vista

plus, my 2nd computer was very slow, it only has 512mb ram and a weak on board graphics card, but nethertheless, i could watch the video

well, i remember having problems playing it for the first time, cause there was some conflict between the jpeg midivid codec and a direct show filter i had installed previously. but after switching the automatic file association for avi files off (in the direct show filter) the error disappeared

and thank you for the review
