avisynth files and DivX

[Maxwel]

I use BSPlayer to play my DivX 5.x files as well as the .avs(avisynth) files that were used to encode them. However when I open a .avs file containing
clip = aviSource("divx.avi")
or
clip = DirectShowSource("divx.avi")
where divx.avi is the file encoded with DivX 5.x, BSPlayer quietly exits. ZoomPlayer and The Core Media Player play the same file. What could be the problem?

OK. Switching to mode 2 fixes the problem.
