The alternative GUI burning app for pdaX would be brasero but that requires a 2.6 kernel and, as far as I can see, gnomebaker should work under 2.4 based pdax. The latest version requires gstreamer 0.10 too though. Has anybody made packages of these already? I installed gnomebaker under ubuntu, dropped my res down to 640x480 and you can use gnomebaker at this res if you turn off its file browser under the 'window' menu.
I should be getting a USB burner soon so if no-one else has packaged this already then I'll give it a go.
