Update: In version 3 of Pocket Tunes we have added support for the Clie remote. If you are still using version 2 Pocket Tunes, please read the paragraph below.
If you are using Pocket Tunes version 2 and would like to utilize your Clie remote, you might try this workaround by Igor Nesterov. He has tried to come to the rescue by creating this program which emulates the Tungsten series 5 way Nav with the clie remote.
