ivtv hints:

1) Make sure you use the latest drivers, not the ones on a v.14 CD-ROM.
wget http://hauppauge.lightpath.net/software/pvr250/pvr250_16_21062.exe

2) When configuring the kernel, you need to enable the bttv drivers.

3) gentoo-sources-2.4.20-r4 and later already have the v4l2 patches
included.

4) You can modify /etc/modules.autoload to load your ivtv driver at
boot.

5) Most applications don't expect mpeg from /dev/video0.  So, test video
with: gmplayer /dev/video0

6) If you run mplayer from a script and close it with the close box, it
won't shutdown properly.  So, use gmplayer.

7) For the US, "Tuner 0" seems to be 4 not 0 as mentioned in the doc:
./test_ioctl -p 4

8) When doing the cat test, xine tracks the recording time wrong.  This
should be fixed in a CVS.  But I haven't checked it.

9) transcode fails on the files, but mencoder seems to work.

10) There is an ebuild for ivtv in the Gentoo forums. (I did not try
it.)

mythtv hints:

1) Make sure to rename the ebuild to mythtv-0.9.1.ebuild

2) Change the ewarn "" to " " in /etc/init.d/mythbackend

3) Add nobody or which ever user you will use for mythbackend to the
video and audio group.

4) You can find out where ./setup is with qpkg -l mythtv:
/usr/share/mythtv

5) If you use Gnome, Alt-tab might help with the focus issues during
setup.

6) keys.txt is not installed by the ebuild, but it is available in the
tarball or here:
http://cvs.mythtv.org/cgi-bin/viewcvs.cgi/mythtv/keys.txt?rev=1.20&content-type=text/vnd.viewcvs-markup

7) Deep in here you find out PVR-250 is "Hardware MPEG Encoder Card":
http://www.mythtv.org/docs/mythtv-HOWTO-19.html#ss19.10

8) The vbi device is at /dev/v4l/vbi0.  But it may not matter.

9) Sound is built into the PVR-250 mpeg stream.  So when configuring the
capture card: Choose "(None)" for Audio device.
