Unknown Format (DivX)

[sies]

When I wanna play this movie I get the message "Unknown Format (DivX)" and the movie doesn't play. I already have Nimo Pack Build 7.
WHat can be the reason of this message or what is the problem?
Is it something with the Xvid-codec?

It looks like you need the DivX codec. Anyway, can you open that file in Virtualdub and go to File -> File Information? Post what you see here.

It can't be the divx codec. I have over 100 movies and this is the first I get this message. If I play an other movie there's no problem. Anyway I'm gonna check what you say. I'll be back!
THanks!!

I can't check on what you ask within the next 3 hours. But I'm pretty sure it was a mpeg 3 format.

I can't upload it into Virtual Dub. This is the message I receive

"Couldn't locate decompressor for format 'DX50' (unknown). VirtualDub requires a Video For Windows (VFW) compatible codec to decompres s video. Directshow codecs, such as used by Windows Media Player, are not suitable"

These are the only details I can get:
resolution: 640x272
bit 128kbps,
MPEG - Layer 3
25 frames/sec
dataspeed 164 kbps.

Hey, thanks a lot. Now it works. But there's one small problem, the movie is very slow. It doesn't run as fast as the sound.

Can you help me with this one?

You have to use Virtual Dub i know that but I am not exactly sure how. I would search the posts for audio and video out of sync.

ok, thanks
I'm gonna try

Good to see the first problem has been solved while I was away.

As to the next problem, there are two possibilities:
1. Audio that is constantly off-synch with the video
2. The particular video file is too demanding for your CPU and hence the feeling that the video seems to be catching up with the audio all the time (with the end result of the video lagging behind the sound)

For the first possibility, this is easily corrected using Virtualdub.
1. Open file in VD
2. Set video and audio tabs to Direct Stream Copy
3. Go to Audio -> Interleave and play around with the value in the 'Delay Audio By' box, until you get the sound right (A few tries will be required)
4. Go to File -> Save as AVI and give the new file a name
This is assuming there is no framerate-related problem, which requires a different method.

For the second possibility, you can check whether the CPU is being overloaded by going to Task Manager (available in Win2K & WinXP only).
1. Play the video and without pausing or stopping the playback, press Ctrl-Alt-Del
2. Go to Task Manager -> Performance. Check that the CPU Usage does not constantly peak at 100%
If the CPU is indeed having difficulty decoding the video, you may need a system upgrade. However, one simple method may just help you.
-. Run the desktop at 16-bit colour and 800x600 (or even 640x480).
-. Disable all playback filters
