I've this question because > this is the first report of that kind. yes i've tested it several times. I've tracked down the problem a little bit. Data is sent to the plugin but the replay thread doesn't start because ScanPayOfPS1 fails. I've commented out these two lines: case 0x0b: // if ((uint_16)dvb != AC3magic) // break; and now it works. > The bitformat over the dvb-card is exactly the same as in the bso > plugin.

I think it's the nonlinear bit. My receiver switches to DD, shows the correct stream information but i get no sound. It's like i've pressed the mute button. Roland
