Video Codecs - Codecs Installed when installing Video Card Drivers Do Not Work
Posted on 2009-04-06
I installed a new Sapphire Radeon HD 3850 AGP video card into my PC and although I believe that the card supports video playback when dual monitors are being used II have had a problem getting any videos to play correctly. It seems to be something to do with what's installed when the drivers are installed.
After getting nowhere with the used XP installation I had before installing the card, I formatted the drive and re-installed XP/SP2
After XP was installed I went into Display Properties and I could change the resolution up high and as I have two monitors, without installing the vid card drivers, the same thing was displayed on both screens at a resolution of 1280 x 1024 on both monitors.
Before installing the video drivers I could only get the same thing on both screens. I installed the Xvid Codec and played a movie and it worked fine, I could see the movie full screen on both screens. But I need to have split screens so I can watch a movie on one screen and do work on the other.
So the only option I could see was to install the drivers. So I installed the drivers and rebooted. Now when I went into Display Properties - Settings I had the option to use separate displays, great (I thought) but then when I tried to play any of my movies all I get is a green screen instead of the movie. (The sound is fine)
Ok I thought, I just need to install the correct codec for the video. So I tried and nothing changed. Then I installed a codec Pack (K-Light Codec Pack) but this made no difference either.
And that's where I'm at. Everything apart from video playback seems to work ok.
I have tried VLC Player, KM Player as well as WMP and nothing shows the video, just bright green where the video should be. I also have Nero installed and although the Video player that is used to watch videos does the same green screen thing. The video priview plays the video ok but just in a space of no more than 2 cm x 1.5 cm
Flash movies play fine but any online video other than flash movies give me the green screen.
I looked in Device Manager under Video Codecs and have all these:
ffdshow video encoder
Indeo video 5.10
Xvid MPEG-4 Video Codec 1.2.1
I tried removing ones before, rebooted and nothng.
When I installed the cards drivers I noticed that it installed ATI Avivo Codecs but don't know what these are or how to uninstall them?
I managed to locate the folder on the Video Cards CD, copied the folder to the local drive and installed it from there and I'll attach this so hopefully it helps. Ok that doesn't work coz of the files it contains .dl_ etc so if it helps I'll upload it to a different place and post the link afterwards.
