I started testing with 6.23.01 pro and it worked fine. I used the Elecard codec and the Flycccam plugin. After a few days, when I selected a channel I could see a change in the size of the black TV window screen at startup and afterwards progdvb looped (can be killed by taskmanager only). I installed progdvb 6.23.02 pro but there was no change.
I suggested the cause in the Flycccam plugin or the in the ended Elecard evaluation time. I deleted the Flycccam plugin and purchased the Elecard plugin, but the loop still exists.
After startup, I can use the help, settings and service function. It loops also when I start a channel search.
Any suggestiones?
