I just installed it with a PVR250 last week. It went fairly smoothly
with the ebuilds on the gentoo bugzilla. You might want to wait a week
or so though, as I see they're in the final stages of getting ready to
include it in portage, and it's likely to be seamless then.

Incidently, just this morning there's discussion on the gentoo-developer
list about creating a bootable liveCD with mythtv and other a/v goodies.

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.

I would be interested in the gentoo live CD, I think.
I have the same Mobo (asus a7n266-vm)and have been
batling with a RH 9.0 install. Although it's working
I would rather switch to Gentoo (I just don't trust
these RPMs).

I would be using the ATI wonder ve that I have, not a
hardware encoder like the PVR250. Any problems
getting that working with Gentoo?

Also, I very new to Gentoo but might wipe RH and start
from scratch this weekend. What "CD" do you recommend
for Mythtv? They talk about "stage 1-3" and recommend
3 for beginers. Is it crazy to want to build
everything. I would like to have a basic system, no
KDE or Gnome (would prefer blackbox, fvwm or another
lightweight desktop).

tia,
josh

I *love* gentoo and would never go back to RH, particularly now that
they're cutting off bugfix support after only one year.

I don't have a Wonder, but I can't imagine why you'd have any problems
with the Wonder if you've got it working under RH. Honestly, I've found
most things work out-of-the-box better under gentoo anyway, since you
have some control over what compile options get enabled. The only thing
I don't like about Gentoo is that KDE takes 8-12 hours to compile. If
you stick to a lightweight wm, you should have no problems at all.

As for the CD's, the only difference is in installation time. The
stage3 install will install a pre-compiled base-system. Stage1 will
download and compile everything from scratch. It's really not any more
difficult to do a stage1 install over a stage3 install (3 extra
commands), but if it's your first time, you might want to go stage3 so
you don't spend 4 or 5 hours doing the install, only to discover it
didn't work, or you don't like it. Also, any upgrades you do later will
be downloaded and compiled from scratch, so eventually the generic
packages that got installed from stage3 will get overwritten when new
versions come out. And, despite what most gentoo'ers will tell you,
there's not that much of a performance difference between something
compiled for a 386 vs. something compiled for a 686.

I really don't think you'll have any trouble. Just be sure to take a
look at the portage guide and rc-scripts guide once you get it installed.

You don't say. Any ideas when this livecd will be making an appearance?
Also, I can just emerge everything from the portage once it's there, right?

Don't know about the livecd, it was only just proposed this morning.
The main difficulty seems to be with the database. I think it will
happen, but there's definately some wrinkles to be ironed out.

Tt should work like any other package once it's in portage. That way
you wouldn't have to bother with setting up a local portage mask or
making sure you grabbed all the dependencies. On the other hand, it's
likely to be marked unstable for a while, so you'll have to deal with that.
