The author of that patch had explained that he was unable to test it.  The patch
was merged into the v4l-dvb master development repository over the weekend, and
Mauro sent a pull request for this patch to go to 2.6.19 a few hours ago.  I 
don't know why this was sent to the 2.6.19 tree without first being tested. :-(

Mauro -- that patch needs fixing / more testing before it goes to mainstream...

Could you please remove that changeset from your git tree before Linus pulls it?

The problem changeset:

git commit 450efcfd2e1d941e302a8c89322fbfcef237be98

Too late. Already pulled and pushed out.

Looking at the patch, one obvious bug stands out: the new case statement 
for SAA7134_BOARD_AVERMEDIA_777 doesn't have a "break" at the end.

José, can you test this trivial patch and see if it fixes things?

Thanks for the fix, Linus... I see that you've already pushed this into git, so
I've added it to my v4l-dvb hg development tree.

Jose, you can use this tree for testing, if you don't want to apply the patch by hand.

Mauro, please pull from:

Oh, sorry about that. :-( I was splitting the patch to multiple ones and
merging it with Jose Alberto's, and apparently this got lost somewhere
in the process...

Yes, this should fix the issue. It passed by my eyes :(

Ok, I've updated also master development tree at 
http://linuxtv.org/hg/v4l-dvb

Pasky,

Please test it also.

Cheers, 
Mauro.

The Avermedia 777 is working perfectly again with the current v4l-dvb tree. No 
more misbehaviours. Looks like you guys addressed and resolved the issue 
quite fast :)
At the moment I can't give the remote control a try because lirc doesn't 
compile against version 2.6.18 of the kernel. If that lirc issue gets solved, 
I will try to use it as soon as I can.

All the best.

  Note that in lircd, you should use the input device driver
("devinput"). The saa7134 driver will create a random input event device
for the events; I use this udev rule to create a /dev/remote symlink
pointing at the right device:

	KERNEL="event*", SYSFS{name}="saa7134 IR*", NAME="input/%k", SYMLINK="remote"

  Furthermore, especially if you have problems with lircd, having the
full-blown daemon for the event interface may not be worth it. There is
a standalone inputlircd package containing a much simpler daemon which
is compatible with lirc client applications but takes the events just
from the input devices. You can run it e.g. like:

	/usr/sbin/inputlircd /dev/remote -g -m 0

  You can find an example mplayer lirc configuration at:
