Looks like I fixed mine - you can switch to the vesa driver as suggested to apply your fix
I ran this update from the unichrome site:
mkdir openchrome
cd openchrome
svn co http://svn.openchrome.org/svn/trunk
cd trunk
./autogen.sh
make
make install
This will install via_drv.so to /usr/local/lib/xorg/modules/drivers/. In order to use it, you need to copy it to /usr/lib/xorg/modules/drivers/, after first backing up the existing via_drv.so, so you can restore it when the new one doesn't work.
This updated my drivers to Unichrome 395 - don't know what this will break though 
the xorg.conf that comes with R5F27 doesn't work for me - i'm guessing the new modelines maybe ?
Here is my working xorg.conf
another option is to copy the via_drv.so from your R5D1 install maybe ?

I have my PVR-350 as output, it runs fine initially, but after several hours of playing video, the screen will either turn "black and green" (as opposed to black and white), and sometimes the overscan gets shifted, or go out of sync.. Rebooting solves the problem. 
I'm using R5F27, PVR-350, PVR-150, nVidia GeForce 4 (splash disabled)

I just want to say, I'm having this exact same problem - running a PVR-350 and an onboard video card (HP D330 mobo) - the previous release of KnoppMyth worked just fine... but this isn't working correctly.

Hi deontaljard,
many thx for your great job!!!
It really works whith my Digitainer CLE266 Via Chipset.
I fixed it so: (with your tutorial)  )
make a std. Installation.
boot with dsl/knoppix cd ...
rename the .xorg.conf to xorg.conf (make ab backup of the original file)
now you have no blackscreen...
setup up your ip adress and connect ....
update the unichrome driver ... (both drivers)
copy the original xorg.conf in /etc/x11
have Fun!!

Not to sound stupid, but I'm having this exact same problem and I'm wondering if there is going to be an official update to fix it? Its happening to a lot of us it seems. My cn700 board worked fine in the last release, and I'm just going to roll back to it until a new version is available I think.
Anyone else agree?
PS - no disrespect to the knoppmyth devs. This is a great distro which has only gotten better. I was looking forward to using schedules direct, thats all.

hi all,
explicit step-by-step for how to fix combining denotaljard & cgiddens' instructions:
make a std. Installation
- when you get the black screen, reinsert CD and boot from it
boot with dsl/knoppix cd ...
- choose Option 7 to quit to a command prompt
- log in as root
- mount your HD so you can access it
$ mount /dev/hda1 /mnt/hda1
- since you're booted from the CD, networking should be up & running
if not, then you need to get networking running
setup up your ip adress and connect ....
update the unichrome driver ... (both drivers)
$ cd /tmp
$ mkdir openchrome
$ cd openchrome
$ svn co http://svn.openchrome.org/svn/trunk
$ cd trunk
$ ./autogen.sh
$ make
$ make install
This will install via_drv.so (and via_drv.la) to /usr/local/lib/xorg/modules/drivers/. In order to use it, you need to copy them to /usr/lib/xorg/modules/drivers/, after first backing up the existing via_drv.*, so you can restore it when the new one doesn't work.
$ cd /mnt/hda1/usr/lib/xorg/modules/drivers
$ mv via_drv.la via_drv.la.sav
$ mv via_drv.so via_drv.so.sav
$ cd /user/local/lib/xorg/modules/drivers
$ mv via_drv.so /mnt/hda1/usr/lib/xorg/modules/drivers/via_drv.so
$ mv via_drv.la /mnt/hda1/usr/lib/xorg/modules/drivers/via_drv.la
now reboot and no more black screen so you can continue your KnoppMyth install/config
$ reboot

I have an epia CN10000 with one of the CN700 chipsets. Even with the new unichrome version, the via driver doesn't still to be picking a displayable mode. I found adding
Option "VBEModes" "true"
to the Device section gets the display to initialize properly.

@outcast2k:
You are my hero today!  Worked fine for me - thank you very much!
But you do not need a Knoppix-CD. Just quit the installation at the installation menu. You can choose to get to the login prompt.
There is also a slight error (for all the Linux-Newbies bemong us). It must be "usr" instead of "user" => cd / usr/local/...
Will last the next time with configuring my new Epia-System (ME6000 with PVR-350)

hi,
after some problems with r5f27(live tv flickers and stuttering, and i have artefacts in the screen 50% cpu load!!), i install the older version of knoppmyth r5f1.
knoppmyth r5f1 takes only 8% cpu load!! and my mythweb frontend works after i made a svn update to the newest trunk.
i can live with the "old" version, i don´t need sirius radio!!
has anyone same the problems??

The symptoms seem identical, with the monitor occasionally flashing like it's trying to auto adjust, but other than that the box seemed locked up (Ctrl-Alt-F1, Ctrl-Alt-Backspace, etc. wouldn't do anything), and I was seeing a similar message when I booted into single user mode and checked the logs. [...] In the mean time, has anyone successfully installed R5F27 on an Epia M10000?
Cerge, have you had any luck?
I'm also using a M10000 and experiencing the exact same issues on a fresh install of both R5F1 and R5F27 - the bootup log shows a few 'failed to find multimedia video card' errors, a few other fails, then flashes trying to get into X before failing with the c7 respawning message.

I updated my openchrome drivers as stated with the exception that the new drivers were named openchrome_drv.x and I needed to specify openchrome as my driver under xorg.conf instead of via. However, now that I have upgraded, it appears that XVMC is not working properly. In all previous versions, when XVMC was working the OSD would be greyscale, now it is showing color. Also my cpu is much higher when showing video. I hope there is a workaround, or patch put out soon.
Thanks,
- Ben
