Anybody knows by any chance if any of the firmware updates increase the amount of files being able to be played by the Iomega Screenplay Pro HD?

What limit are you running into? There is a file limit on the root of the drive, so if it is related to the number of files, consider putting all of those into a subdirectory. No firmware update I'm familiar with changes the number of accessible files. --JCoug 15:02, August 18, 2011 (UTC)
