Hi everyone,
when testing an upcoming show in the studio today I have encountered a very strange thing that I could not resolve. Maybe somebody has had something similar and can point me to the problem:

On one of three identical Display-PCs movies with H264 Codec do not play. They appear on screen with the first frame or maybe play for a second or so and then freeze. All other content on top of the H264-video plays OK. MPEG-Video plays OK, too. It´s just the H264. Judging from the HDD-LED the movie is played, the LED shows traffic when playing only the h264 part of the show.

I´m using Win7/32 with the new 5.2 version.

This is what I did so far without seeing any changes:
- check an old show that worked fine previously with 5.1. It has the same problems
- reinstalled a working image
- uninstalled WO and did a fresh install
- uninstalled Quicktime and did a fresh install, also stepped back one version from 7.7 to 7.69
- unistall and reinstall the grafics driver, also tried 3 versions of catalyst: 11.9, 12.1 and 12.3

The only thing I didn´t do is reinstall WO5.1 and try and old show. This is probably no option because I made the show that I need in 5.2, so I guess I´m stuck to the new version anyway.

It somehow points to a hardware defect. Is this possible? To check that I would need to swap components between a working PC and the bad one, no time for that now... Or is there any other likely explanation? All suggestions are very welcome!
Regards,
Michael

Hi Michael!

The obvious thing to do is to clone the problem PC from one of the working units.

Best regards,

Hi Frederik,
I´ll do that tomorrow after it´s set up at the venue. But I do not have much hope that it changes anything, since I already did a restore from the master-image of our display-pc´s without anything changing....
Regards, Michael

Please do. I can't believe that identical content will play on two machines and not on a third, which is 100% identical with the other two. If you still have the problem switch computers and see if the problems follows or if it stays on the same screen.

Best regards,
Fredrik S

Are you receiving any errors when going online or updating?
Possibly a file is missing or no longer correctly attached to its media object?
Would generate an error if so.

Hi

And? 3rd Computer running perfect?

We also have one or two "lazy" computers! Than we realize: The Hardware isnt 100% the same!

Could it be possible in that case?
