Thank you for clarifications. Now all is clear about playing.
I am building a plugin which needs to work on all images, not only OpenPLi. So, i can't just edit/change enigma2 and machine recipes and make home build.
But finally i see the point and concrete reasons why some hisillicon boxes can/can't play 4097.
That's for the playing.
For chanaging info on Infobar...
I'll try to find an alternative way for my goal. Maybe there is a way to "forbid" Infobar to change information on Infobar on zap, regardless of player.
I do made WHERE_SESSIONSTART which in background follow every zap with ServiceEventTracker, i just can't find a way to stop Infobar from changing the info.
