AVI files playing upside down/back to front

**chrsthorn** · February 24th, 2003, 02:37 PM

Hi.

Recently, every time I have tried to play an AVI file, it plays upside down and back to front. I've had a search on the Internet for resolving known issues, and I've had a look through VirtualDr, but nothing has helped.

I used the Start > Run > "RunDll32 advpack.dll,LaunchINFSection C:\WINNT\INF\wmp.inf,Uninstall" method to uninstall Windows Media Player 9 Series.

I've downloaded and installed the following in the hope that they resolve the issue:

Windows Media Player 9 Series (latest)
Windows Media codecs (latest)
DivX Bundle 5.0.3
Zoom Player

I still have the same problem though. All of the above programs either play the files back to front or not at all.

The only major changes to my computer recently have been the installation of Apache 2.0.44, DirectUpdate 3.5.8 and RhinoSoft FTP Serv-U FTP Server.

If anyone could give me a hand, it'd be most appreciated.

Hi.. have a look at this thread with the same problem. Ultimately the fix was changing colors from 16bit to 24bit.

Well, I'm already running 32-bit colours. I have Windows XP Pro, so how do I access the so called "Multimedia" controls in Control Panel? I don't have them!

I don't have winxp but in 2k it's in control panel/sounds&multimedia>hardware>video codecs/advanced

Otherwise someone who uses winxp will probably be along to point you where to go.

I've found the video codecs in Device Manager. I've deleted the Microsoft MPEG-4 one, and the DivX 5.0 one, and a few others I recognised as having been downloaded, but now I have the following list left (picture posted on website) http://cthorn.homeip.net/codecs.jpg. Is it safe to delete all these and start from scratch, then install the WM Codec pack?

You shouldn't have to get rid of those older codecs. Try playing an avi file that uses one of the existing codecs and see if it plays correctly. If it does then reinstall the Divx codec(s) following the instructions in the link.

**chrsthorn** · February 24th, 2003, 03:14 PM

OK, but how do I find out which codec the avi file is using?

In older WMP players it's in file/properties/advanced. Probably the same or similar in wmp9.

There's also this handy, free little program that identifies codecs in films..

Oh cheers. I was looking for that program to see what it does! I found out that my video codec for AVIs is called ffdshow or something, from www.doom9.net. Just going to have a mess with it all now.

Thanks loads for the help, btw!!

Have uninstalled all the video codecs from Device Manager, rebooted, but the stupid things reinstalled themselves during the reboot, or something! I am absolutely stumped. Deleting the codecs didn't work, updating them, downloading loads of different ones... etc. Nothing seems to work.

I guess the other option is to think what might be causing it? A virus/bug of some sort? I can't afford to do a clean uninstall/reinstall of Windows at the moment, too much work and not enough time... and not enough spare HDD space or CD-Rs to back everything up! Aaargh!

Have a look 'round the microsoft WMP newsgroup and see if anyone has the same problem...

Did the problem start suddenly or after you installed something?

**chrsthorn** · February 25th, 2003, 07:34 AM

The problem seemed to start suddenly, although, as I said earlier, I had installed a few server programs and things like that. I hadn't, however, installed anything that should directly use a video codec (if you see what I mean, e.g. QuickTime or something).

Thanks for the newsgroup address - I'll have a look at it.

Aha! It's all sorted now. I got a reply in Microsoft's "Windows Media" newsgroup, and someone suggested that hardware acceleration was off, which indeed it was. That made me think of running the DirectX dialog (Start -> Run... -> "dxdiag"), and as it was loading I got a message like "Hardware acceleration is disabled whilst Microsoft NetMeeting is running." So, I turned off NetMeeting, my monitor blinked, et voila! AVIs worked perfect!

I suggest that if anyone has a similar problem, try running the DirectX dialog program. Try disabling any webcam programs too.

Cheers for the help people.

Thanx for posting the fix. Does starting netmeeting again reset hardware acceleration to off and make the vids run backwards again?
