I am running IDL5.1 under Windows NT 4.0 and am trying to create an MPEG
file. I have a set of images which I can load and play using XINTERANIMATE.
Everything looks fine. I then push the "Write MPEG" button. Again, everything
looks ok with the file being written to disk. However, when I try to play the
file back using a QuickTime Movie Player, I get an error saying it cannot
open the file. When I try to insert the MPEG file into a Microsoft Powerpoint
97 Slide presentation, I get a message saying Powerpoint found an error that
it can't correct. I've also tried creating the MPEG file using the MPEG_OPEN,
MPEG_PUT, MPEG_SAVE, and MPEG_CLOSE procedures as described in the IDL5.1
help and I still have no success reading the file back. Has anyone
successfully created an MPEG file under IDL5.1 directly or using
XINTERANIMATE?
Finally, I've tried creating an MPEG file by EXACTLY running the example given
in the IDL5.1 help for XINTERANIMATE (which uses the IDL bundled abnorm.dat
data). Again, it seems to create an MPEG file (76 KB) when I press the "Write
MPEG" button but I have no luck reading it with the two MPEG reading capable
programs mentioned above. Am I missing something?
Thanks.

Thanks to the folks at RSI (as well as several others) who suggested a
solution to this problem which does indeed seem to work. The suggestion was
to upgrade the ActiveMovie component of Windows NT. I did this by downloading
the latest DirectX 5.2b run time package from the Microsoft website. The file
is called DXMWEB.EXE and is 3.86 MBytes. For anyone interested, the URL is
http://www.microsoft.com/directx/resources/dx5mediaruntime.h tm
It took me a bit of hunting around on the Microsoft site to find it.
Initially I grabbed a file called DX5ENG.EXE before realizing that
installation was for Windows 95. So, be careful out there.
After running the install, I was able to insert and run the MPEG file created
from IDL into a Microsoft PowerPoint presentation. Problem solved.
Thanks again and I hope this info helps somebody else out.
Cheers,
Robert Pina
