 "cscd_1_0_306_306_lzo.avi" file was encoded by the "CamStudio Lossless
 Codec 1.0"

 "cscd_1_5_306_306_lzo.avi" file was encoded by the "CamStudio Lossless
 Codec 1.5"


 camcodec.dll 1.5 is able to decode both of the files correctly.

 FFmpeg fails to decode "cscd_1_0_306_306_lzo.avi" file.

 What is a reason for this I don't know, but I guess that both files should
 decode correctly with FFmpeg's decoder just like they do with the original
 thing.

 Also both of the files decodes to identical output when I export them to
 RAW in VirtualDub: File->Export->Raw video...
