[linux-dvb] Re: Announcement, new driver features

["Peter Seyringer" <dvrproject@seyringer.priv.at>]

Hello!

Is it posible with the new firmware to write direct in the framebuffer
memory of the mpeg encoder. This would be a great future to implement some
programs without any complicat algols (like converting them into MPEG1 oder
MPEG2). That makes it also posible to implement a WEB browser oder same
games on the dvb-s card :).

Peter
