[mythtv-users] Tuning a Plextor TV402U

Graham,

I managed to get mythtv working with the TV402U, but I stumbled into a 
few hurdles too. I used the kernel-multimedia-2.6.11-9.mm.2mdk, which 
includes the go7007 drivers. The next step was getting the firmware 
loaded. These were the steps I took:

Copy the hotplug scripts:

    cp ~/wis-go7007-linux-0.9.4/hotplug/wis.usermap-ezusb
    /etc/hotplug/usb/wis-ezusb.usermap
    cp ~/wis-go7007-linux-0.9.4/hotplug/wis-ezusb.in
    /etc/hotplug/usb/wis-ezusb


Copy the firmware:

    cp -R ~/wis-go7007-linux-0.9.4/firmware/* /lib/firmware/


I needed to modify the wis-ezusb script a bit to get it to work:

    diff ~/wis-go7007-linux-0.9.4/hotplug/wis-ezusb.in
    /etc/hotplug/usb/wis-ezusb -ur

The fxload package needs to be installed, and the 
/etc/hotplug.d/default/20-hal.hotplug symlink removed, otherwise the 
firmware won't load. This may be a Mandriva issue. See:

http://groups.google.nl/group/alt.os.linux.mandrake/browse_thread/thread/e5465be0c95b2231/f5aef2e102d7794f?q=go7007&rnum=2&hl=xx-elmer#f5aef2e102d7794f

I then managed to capture a .avi file with the "gorecord" application. 
Then I went to mythtv, and when I pressed "c", the input would change, 
but what I saw on the screen didn't. I noticed the the following 
messages (unsupported ioctl) in syslog:

My hunch is that mythtv may be doing something wrong when trying to 
change the input connections. The trick I used was to record something 
with gorecord, on the input that you want to use in mythtv. Then, turn 
on mythtv and you'll be able to use it.

Stefan van der Eijk

PS: CC-ing Mandriva's cooker list, perhaps we'll get this hardware 
supported out of the box one day...
