Ahah... I think I can answer my own question about the DV codec. It is a case of Type-1 versus Type-2 DV AVIs.
- Trying to use DV codec compressed AVIs causes PD to crash. Through the
wonders of open source, I've tracked this problem down to a NULL return from AVIStreamGetFrameOpen(m_streamVid,NULL) in pix_filmNT :: realOpen() from pix_filmNT.cpp
This suggests that the AVI/Video For Windows system can't find an appropriate decompressor on my system. However, the same clips play just fine with Media player or other apps on the system. I have no problems in GEM using cinepak or a couple of other codecs that I've tried.
