[vdr] Re: DVB over emu10k1 !?

[Onno <onnok@web.de>]

Hi,

good to know, unfortunately i have not jet learned
c/c++ but i will try it to see if my poor knowledge
is enough to patch bitstreamout to put the stream to
disk/pipe, i used to be a bash'er but one never knows,
i start to like the idea of adjusting real code to my needs.
(and giving it back to others enhancing my tv pleasure)

ok, but a set of cmi87xx card + 5.1 speakers is around 70€

hmm, thats why i would use mplayer :
- no care about oss/alsa
- volume control / audio filters
- cache/delay settings

OT: did you know that belgium switched adsl to 3mbit
at no notice or extra charge, they just did it !
