AW: AW: Trouble playing videos with MS DirectShow LC 8

[Phil Davis]

If you pick the video file with a file dialog and set the filename of 
the player to "it", will it play then? If so, maybe you're having a path 
issue.

I have an old nice tool, called gspot, which usually tells me everything about any video, but it doesn't work with theses H.264 mp4's.  I was on the intel site and downloaded a media sdk, installed it on one of those not working machines, but without success. But actually I don't even know, if that codec is part of that media sdk, they don't describe the detailed content. So it was a shot into the dark and I didn't found yet a dedicated download for that codec.
