[linux-dvb] dvbtune / dvbstream with recent CVS

[Gavin Hamill <gdh@acentral.co.uk>]

Hi again :)

Has anyone else noticed that dvbtune 0.5 is broken with the v4l 
All-in-one patch on 2.6.10-rc1 at least?

_exit(-1)                               = ?

Yet the 0.5 version of 'dvbstream' is unaffected and tunes OK, and both 
have an identical 'tune.c' - I really don't understand what's going 
wrong :/

Cheers,
Gavin.
