MPEGDecoder.dll problem

Zitat von Beschreibung der MPEGDecoder.dll

number of frames
This should always be 0 as a default. But can be used to force the decoder to return a certain number of frames. MPEGSource can not correctly create d2v files for MPEG-1 yet, so use this to input the correct number of frames.
A value of -2 can also be written here. This means no d2v can be used and therefore only files can be inputed in the first parameter. From the files specified Directshow is asked to get the correct number of frames.

Du laedst Dein MPEG-1 Video also am besten zuerst in VirtualDub(Mod), schreibst Dir dort die korrekte Anzahl Frames raus und traegst das in der MPEGSource() Funktion nach.
