[linux-dvb] Re: DEC 2000-t - anybody in Germany successfull?

[alve <ulfonk_mennhar@gmx.de>]

these are exactly the same as my problems ... if anyone can trace them, 
I could send some logs or something, just tell me what you need. I tried 
to figure out some things myself but still have no clue.

And about the scrambled sound: on my machine mplayer has a problem with 
alsa sometimes ... check that first ("-ao sdl" resolves it, if sdl is there)

cheers
