[mythtv-users] LiveTV, FC4, kernel-smp-2.6.15-1.1830_FC4

Wed Feb 8 03:12:57 UTC 2006

At least one other person reported something strange about this, but I
thought I would let people know that the latest FC4 kernel
(kernel-smp-2.6.15-1.1830_FC4) seems to do weird things with live tv
in myth.  I am using mythtv .18.1-117 and ivtv-4.2.101.  Strangely,
the channel seemed to be stuck on a non-signal channel (had to boot
into windows, change the tuner chanel with Hauppauge's tool).  Then in
Myth, I see TV again . . . but, I could not change the channel.  It
let me input and press enter--it paused like it normally does, then
the brief guide came on listing the program transparently over the
video, only the video was the same channel.

When I bring it back down to kernel-smp-2.6.14-1.1656_FC4, the problem
goes away.  One of the key errors seems to be tveeprom module not
loading:

In all, there could have been some pretty key changes in the new
kernel.  I will try to dig into it a bit later, as there will be
issues as people update.  I also noticed some weird i/o errors on my
dvd drives, but I am not yet sure if it was this kernel or a bad
cable.
