Thank you!!! I have both Delfina Lite (Zorro) and Delfina Flipper (ClockPort) and they behave differently!!! Unsetting the DELFINAMPEG on the machine with Flipper (delfina.library v19) works now again... I have been scratching my head for a while why the DelfMPEG-player worked and MHI with dmdev did not... THANK YOU!
