Does anyone have any discrete codes for the Panasonic DMR-75 DMR-85 series so that I can select HDD and SD and on-board DVB tuner without having to cycle through them one by one?

I have found that the Pronto database code for "DISC" jumps straight to the DVD-ROM drive from either of the other sources. But I cannot find any codes that jump to the other drives or the tuner.

[edit] I should point out that I can jump to the DVD-ROM and cycle through from there, but it doesn't look good to see the drives skipping slowly past every 4 seconds. It would be nice to jump straight to the required source without the cycling.
