.mpg not playing in Microsoft Powerpoint

Hi,

I have a Dell Latitude that has an ATI Raedon 7500 display adapter.  I have a presentation that has a .mpg.  The powerpoint and .mpg are located in the same directory.  I walked through the steps of inserting a movie from file and playing automatically and it works great.  However on the Laptop I just get a black square.  I tried moving hardware acceleration to none but still no video.  Any suggestions?

Thank you,

Frank -

Hi fferrel,
----------

if you walk through the same steps on the laptop [not clear from your comment] does that change anything? it could be simply that the movie is pointing to the folder on the desktop machine

Frank,

is the 'black square' only on the laptop screen - or when you are projecting from the laptop, or when you connect an external monitor to the laptop?

Does the mpg file reside in a really long total folder length?

e.g.
c:\documents and settings\your user name\my documents\my presentations\etc\etc

Cheers

Yes it is a long path.  How do I make it into just the file name?

This .mpg imports and plays fine on my desktop but not on the laptop.  I tried importing another .mpg on the laptop and it worked.  Could there be something wrong with the file?  Why does it still work on my desktop?

Thanks

yes it looks like a configuration issue especially since the file plays ok on the desktop

di you import the file on the laptop from a directory where the presentation resides that would solve your long filenames but if another mpg worked its strange that that should be the problem looks more like a codec issue

Yes I resides in the same Directory as the .ppt.  I updated media player(which it plays fine in), video adapter, and office.  I am stumped.

Frank,

On the laptop...

make a new folder

c:\testing

put the mpeg file in the same folder you just name

- start powerpoint
- on a blank slide
- insert menu > movies > from file
- locate mpg file from c:\testing\
- insert it
- slideshow menu > view slideshow

does it work?

If it does not work... where did the mpg file come from?
did it come from a digital camera, or from 3d software or what?

Cheers

Ok, it came from a dvd camera.  I used movie maker to extract it off the CD.  I suppose lack of information will confuse the people trying to help.  I renamed the .vob file to .mpg.  I assumed since it worked on my desktop and that other mpg's work in the .ppt - that this should work.  It doesn't.

Alright - this is what I did to fix it.  I renamed the file back to .vob and converted it to an .mpg.  I works fine,  I'm still not sure why it worked on my desktop.  Even though many say renaming .vob to .mpg works, it may cause problems down the road.

Thanks for the replies.

simply renaming from one to another format is something i do not trust anytime but that could have something to do with my thinking why you would need another extension if the binary was really the same

we had a question here a weeks back also working with vob format i thought it had a companion file and both together made up the media file but i'm not sure if this is the case here

did you do the conversion on the desktop or the laptop this second time?

thanks for the grade, but it would've been better to start a next time with all info/background in the first comment that would give us all a better footing in helping

I converted it on the desktop with a trial version of (blazemp) I think.  I did a search for .vob converter.

Just playing around I also converted the .vob to .avi, then opened the .avi in movie maker on the laptop and converted it to a .wma.  That also worked.

Why have .vob if it's so similar to mpeg2 ?   Is it some open source file type?

no, according to file ext info
http://filext.com/detaillist.php?extdetail=VOB

A VOB (Video OBject) contains several streams multiplexed together: Video, Audio and Subtitles. Video is MPEG-2, audio can be AC-3, Linear PCM, Mpeg 2 multichannel or MPEG1 layer2 2 channel audio.

so what probably happened in your case is that the VOB file contained MPEG2 for the video and maybe something else for audio and both together got converted into a correct mpeg file and avi file for that matter

somehow it worked on the desktop just renaming which in light of what you did later is still a bit of a mystery where you can say that the desktop mpeg player [i assume windows media] did take the file correctly and on the machine you moved this file to didn't take it as complete or correctly encoded
