OK in some players, not in others

[terrypin]

I compressed an AVI with DivX (6.2.5) using VirtualDub (1.6.14). Same sort of operation I've done many times before. But I cannot understand why it runs OK in only some of my players.

WMP9: Jerky
Media Player Classic: OK, then stops for 10 s, then OK.
IrfanView: Inconsistent. Reports it must close - but then plays OK!

PowerDVD: OK
Nero ShowTime: OK
VLC Media Player: OK

Is this sort of inconsistency common? What might have caused it, and is there anything I could try that might fix it please?

WMP9, WMC and IrfanView would all use the same dshow decoder. PowerDVD probably has an included MPEG-4 decoder, Nero definatly does and VLC doesn't use dshow at all.

Thanks, but what's dshow, and its significance please? All this is mostly still a dark art to me...
