Hi @newleader,
Thanks for your interest, i bought a qwerty remote afterall and started to play.

Your remote control does not work with any enigma2 images other than Vu+ ones, so to have the qwerty part working you need to use an original image.
You can check this thread for more details about why is not working

All other images are based on OpenPli which have did an awful "workaround" to fix their enigma2 image to work on Vu.
The qwerty remote control can work with almost all Vu+ receivers, try to find the user manual for your remote and put the remote in the right mode for the vu model on which you want to use.
At the end i found why almost nobody it is interested in a such app, well.. because the qwerty remote does not work due the OpenPli workaround and nobody use the original images....
Unfortunately i didn't had time to fix their "workaround" yet and probably i will not have time very soon.
Best regards,
Marc
