<DIV><FONT face="Courier New" size=2>It sounds like you are running MythTV on
the framebuffer, but aren't using the Hardware decoding. Go into the Setup
menu, and select the Playback Setup. The second page allows you to
enable Hardware 350 decoding. Make sure that's enabled.</FONT></DIV>

<P><FONT face=Tahoma size=2>I am new to Linux so please bear with any
ignorance that I may display. First off, here is my hardware setup:</FONT>

<P><FONT face=Tahoma size=2>I loaded the latest nvidia driver for my graphics
card. I installed the latest ivtv alpha release, which supports tv-out for the
PVR 350. To compile the driver I had to change the line in ivtv-fb.c that
reads "pte_offset(pmd_offset" to "pte_offset_kernel(pmd_offset". I modified
the XF86Config file for dual-display as noted in ivtv-fb.c, using the
appropriate framebuffer device, which is "/dev/fb0", and the appropriate
BusID obtained using "lspci -v", which is "0:10:0". I updated modules.conf as
follows: </FONT></P>

<P><FONT face=Tahoma size=2>I set modules.autoload to load the modules in the
following order nvidia, ivtv, ivtv-fb and saa7127. I downloaded and installed
MythTV version 0.12, enabling native ALSA (I have the latest drivers
installed) and LIRCD support. After booting up the system, I can see KDE on
both my monitor and the TV. When I run Myth on my monitor everything runs
fine. I can pause live tv, set recordings, record, playback, etc. with no
problems. However, when I run Myth on the TV, everything works fine, except
that live tv and recording playback drop frames and no sound can be heard.
Here is what mythfrontend reports back to me:</FONT></P>

<P><FONT face=Tahoma size=2>Shouldn't the PVR 350 be shouldering the bulk of
the video processing? I've heard other's say that all works great for them
with respect to PVR 350 TV-Out.</FONT></P>
<P><FONT face=Tahoma size=2>I apologize if I am a bit long-winded, but I
wanted to give you as much info as possible to work with. Once again, I am
pretty much a newbee when it comes to all of this, so please keep that in mind
when responding.</FONT></P>
