Michael:
First off, thank you for creating great tools. When you mentioned filenames I took a look at the files in question and tried renaming them to something more standard: s0Xe0X.avi. Still seemed to run into the issue where on first click Mount Image attempts to load them but on second they play fine in Media Center.
While I do have My Movies, I still use Mount Image via the Videos library on occasion. In this case I wasn’t trying to play an ISO prior to playing the avis.
It’s not really a big deal, just strange that on first click Mount Image gets fired off and on second things go as expected. Again, thanks!
