Just to lend some support, I'm using Mandrake, PVR250, and mplayer 1.0pre7
complied on my machine, and have the same exact problem. Mplayer fails with
v4l2: ioctl request buffers failed: Invalid argument. I also can get video
if I take the tv:// part out and just use /dev/video0.

First off, thanks to all who responded to my last post. Unfortunately the
suggestions didn't help.
To recap:
Freevo 1.5.3
PVR 250
FC3
IVTV
MPlayer 1.0pre7 complied on my machine
The problem: Can not watch tv. Any attempt to use mplayer tv:// style
commands results in mplayer crashing as follows::

- MPlayer crashed by bad usage of CPU/FPU/RAM.
Recompile MPlayer with --enable-debug and make a 'gdb' backtrace and
disassembly. Details in
DOCS/HTML/en/bugreports_what.html#bugreports_crash.
- MPlayer crashed. This shouldn't happen.
It can be a bug in the MPlayer code _or_ in your drivers _or_ in your
gcc version. If you think it's MPlayer's fault, please read
DOCS/HTML/en/bugreports.html and follow the instructions there. We can't
and
won't help unless you provide this information when reporting a possible
bug.
====================================================================================
I've looked into the "v4l2: ioctl request buffers failed: Invalid argument"
error and found people saying that ivtv will not work with mplayer tv://
commands. Is this out of date? It would seem to be because it appears the
Freevo will default to using mplayer and tv://.
I can watch tv by simply having mplayer go straight to /dev/video0. I also
dug the old ivtv_basic_tv plugin out of cvs and tried it. It works like a
champ, but it is deprecated. According to the cvs message, it has been
replaced by the tv.mplayer plugin as it has ivtv support. If that is the
case, have I missconfigured something that is causing the tv.mplayer plugin
to output the wrong mplayer command (should not be trying to use tv://
format)? Is the command correct, but there is something wrong with my ivtv
or mplayer?
Are there any good guides to setting up pvr 250's with Freevo? I can't seem
one, and what I can find gives the impression that it should just work
leaving me feeling like an idiot for not having it working (idiocy on my
part may indeed be the problem). I have been using the Fedora Myth(TV)logy
site at wilsonet.com. I even reinstalled FC3 and went through the whole
setup again just in case I screwed something up.
Thanks in advance!
