Why no video but audio ok

By rckowal ·
O.S. is Windows XP Media Center Edition (same as XP Pro with extras).

When I playback known good commercial &/or home movie DVDs using Windows Media Player 11 for XP SP2 or RealPlayer 11, I can hear the audio OK but there is no video.

If I playback the same DVDs on the same PC using VLC Media Player, or a stand alone Sony DVD player, both video & audio play OK.

When playing back movie files stored on my HDD, both W.M.P. & RealPlayer will play both video & audio in AVI files but will not play the video if the file is an MPEG. I've checked the codecs of the movie files using GSpot &/or Mediaifo utilities. Both report that MPEG 2 is installed & no codecs are missing.

Both Windows Media Player & RealPlayer were working fine until very recently. In the meantime, my PC encountered problems so I had to restore it from a recently saved Acronis BackUp. There were also some registry issues concerning video editing software that had to be dealt with as well.

I've been trying to fix this problem for several days now without sucess. What?s going on here & how can I fix it?

Best regards, Richard

SP3 for your windows box, then I would try uninstalling and reinstalling WMP11

Edited: I would also download CCleaner (free), use it to help clean up your registry.

Thanks TK. I was in error when I said I had SP2 installed - it's actually SP3.

I use CCleaner some what regularly to keep the registry clean.

If the other ideas posted here don't work, I will try re-installing WMP 11.

Thanks again, I'll try installing xvid mpeg4 as you suggested. Do the Google downloads provide an automatic installer? If not, how & where would I install it?

By the way, a quick scan using GSpot didn't show this codec - interesting! With my very limited understanding of the subject, I would have never thought that xvid mpeg4 would be needed to just playback home made mpeg2 files or DVDs.

RE: "no codecs are missing" ...

Only means that GSpot (or whatever other utility you've used) has detected a codec.

It doesn't mean that the codec is anywhere near up to date. Get the latest codec pack and install it.

*VLC and other stand-alone players contain their own codec packs. These packs are not shared with the operating system.

Edited for *
