Broken Mpeg2Dec??

I have been writing a delphi app that produces an automatic menu for svcd from an mpeg video file.This program allows different backgrounds fonts colours etc, makes the appropiate chapter info (in xml) and burns the complete bin file to disc. This has been working wonderfully during the development and after deciding to make some cg intro and change disc mpg's (using various 3d packages) I have found I can no longer load an mpeg file into my program or the vidframe delphi program by aquaplaning (from which the playback and capture sources origanate). The avi files load up ok as do the mpeg in dvd2avi, power DVD etc. The error I get is :- External Exception E06D7363 Maybe someone has had this error (i suspect this has happened after one of the 3d programs changed the MFC42.DLL or maybe another DLL). I have tried installing a new MFC42.DLL and various MPEG2DEC.DLL but the problem persists.. Any body got any surgestions

update 

After updating various dll's (Msvcrt.dll, Msvcirt.dll, Mfc40.dll, Mfc42.dll) I discovered that when running the Direct X Diagnostic program DxDiag.exe I got the same error when pressing MSInfo, Troubleshoot etc on the last page. This gave the following error:- Msvcp60.dll cannot link to Msvcrt.dll After searching on the web I discovered that Visual C++ 6 updated this problem in SP3 onwards, If anyone has this distribution file (without the 129Mb Download) or knows of a possible solution please let me know. I have even tried running a working copy of my program on a clean install of win98 but with now success. I will post again if more info is established or (hopefully !! I cure this problem)

Update 2 

installed the latest vc++ sp 5, I have not got the error in the dirctx diag program now but my program and (vidframe source code) still crash with the same error!! so here we are := clean install of win98, ms directx sdk, clean install of delphi,vc6++ and C Builder 5. Power DVD installed (so the mpg file plays in media player), avisynth installed (just for the hell of it!) Currently looking to recode in VC6 using MCI Any ideas??:confused:

Broken Mpeg2Dec (Sort of)
