In the Tutorials documentation supplied with Avid FX 6 there is a reference to a Tutorial_Media.zip file available from boris/downloads. This file contains images for use in the tutorials. The first Tutorial refers to Columns.pct file. When you try to load this still image file into Track 1 as instructed you get an error message saying that the file type is unsupported.
It will also not open the Water.mov file from the Movie selection. *.mov is not listed as one of the available file types. It only lista *.avi and *.mpg.
This did not happen in version Avid FX 5.8
