Unfortunately, the DirectCD 22.214.171.124 does not allow a choice between Quick Format (Mt. Rainier/EasyWrite) and Full Format when a Mt. Rainier capable burner is used, i.e. the Liteon LTR 52246S with 6SOF firmware.
Drag-to-Disc (packet writing) in Easy CD/DVD Creator 6 allows a choice between the two formats with the same burner and firmware, and also allows the enabling of compression with a Full Format.
If you start a Mt. Rainier recording on one computer, it will be readable but not writable on another system that doesn't support Mt. Rainier. If you want a disc to be writable on a non-Mt. Rainier system, it must be fully formatted. This means you have to use a writer that doesn't support Mt. Rainier with this version of DirectCD for writing transportability.
Depending on your burner, it may be possible to flash your firmware to an earlier version without Mt. Rainier support. I am not suggesting this as a good solution, but it may be useful as a last resort.
