Hasta La Motion!

I am using Nuke to convert *.exr files (from VRay) to scanline.

so as you would I set up my write node all channels, set my compression, rename the file adding an sl to the name and away we go.

now I have two problems that I run into.

firstly on occasion nuke refuses to read these files and the read node error out..

secondly if for example i exited the comp and later went back to that comp to do further work, when it is re open I get the below error for the write node that did the conversion, this is with all compression types for *.exr files

"write1.file_type : Bad value for compression : LZW"

am running mac osx 10.5.7 and nuke 5.1v5
