Already tried a search about this on google, through YouTube, and through some links with FireFox.
System Details: FireFox Browser version 3.6.14, and now also on Internet Explorer version 8; Windows XP s.p. 3, YES fully updated; Norton Internet Security 2010, YES also fully updated - the definitions.
Problem Description: YouTube videos only will play the audio portions but the video screen part stays all black, so no video. This is only when trying to play Youtube videos. I have tried other video share sites like Vimeo and DailyMotion, and they work. This is a sudden problem, not more than one day old.
I tried doing internet search and looking through firefox links and some youtube information links, but not really much help. FireFox was updated on the machine two days ago and no problems noticed; next day, the all-black video display for YouTube videos began to occur. One suggestion was to clear all cookies and try again. This worked, but only for single play; after than, then only black video display while audio played. I tried changing and disabling Hardware Acceleration, but this did nothing for bringing back video play in YouTube videos.
I tried YouTube on two other machines and videos play well, both video component and audio component, but these other machines only have I.E. 8 as the browser. Not sure then what to think. Problem seems to be only on one machine, using XP sp3, with both IE 8 and FireFox 3.6.14 and only for YouTube videos, not videos from other sites.
I want to know anything that anyone knows, if anything definite IS known. So far, seems like FireFox (Mozilla) does not yet know enough and YouTube does not know enough.
