Hi,

did you try saa7134 ir_debug already?

Gerd's input utils on cvs.bytesex.org are great.

You are able to dump keymaps and load them modified at runtime with
input-kbd -f file 2, 2 as sample number for the event device of the
remote.

Cheers,
Hermann

Well the actual keypresses are minor problem. Below there are some
checks for bits in decoded code, so if we'll remove they keys will work.
But first of all, we need correct decoding. For example, see checks for
RC_START (rc5) = 3 and RC_ADDR (rc5)=0. Now with toggle on bit 2 instead
of bit 3 we have something wrong.

Mauro,

Please pull from http://linuxtv.org/hg/~hverkuil/v4l-dvb

for the following 4 changes:

- Fix register checks, fix resize bug.
- VIDIOC_INT_S_REGISTER is IOW, not IOR.
- VIDIOC_G_SLICED_VBI_CAP now accepts a v4l2_buf_type, make it IOWR
- Add cropping support to v4l2-ctl, set buf_type in sliced_vbi_cap 
query.

Use VIDIOC_S_FMT or tweak the vertical resolution directly in the sysfs 
interface and you can set it.  The pvrusb2 driver will pass that 
information through to both cx2341x and saa7115 (for 29xxx devices, or 
cx2341x and cx25840 for 24xxx devices).

Well, not quite. Do you want to process this patch or shall I do it? :-) 
With this patch S_FMT works again.
