Hi guys, This is my first post on this forum and it looks like a ocean of knowledge, which is what I've been looking for. I've have an issue with a friends PC that I said I would look into for him. Basically he can open video files mpeg, avi, mov etc... when loading them from his hdd but as soon as he goes online to say bbci player, youtube, myspace etc he cannot view the video and his PC locks up and you have to pull the power to restart as task manager won't open to close the browser. He's tried explorer and mozilla but the problem appears on both browsers. Strange thing is if the stream is set to open with mediaplayer it runs fine, so it's leading me to believe that it's a codec issue. I've set default player as mediaplayer but still BBCi player won't I've sorted him out with the lastest Divx and drivers/firmware versions for all hardware. I know youtube uses a flash player so is there a specific codec for media player to run flash streams? All comments welcome as I'm starting to rn out of ideas. Thanks for reading.
