This thread is a fork ofhttp://www.avsforum.com/avs-vb/showthread.php?t=1025170
to focus on the Kworld ATSC 115 tuner card on Myth.
I installed Mythbuntu 8.04 from scratch on the same hardware posted at the top of that thread,
BioStar NF4 Ultra-A9A mobo (already had socket 939 x2 3800 cpu)
AMD X2 3800
Nvidia 7300GS PCIe 256MB
1 GB Crucial PC3200 DDR
Maxtor 120GB OS drive
Maxtor 200GB data drive for recordings
Packard Bell Fast Media Remote with serial port receiver- works fine
downloaded the firmware script perhttp://www.mythtv.org/wiki/index.php/AVerTV_HD_A180
then used the commands
chmod +x get_dvb_firmware
to download the firmware. You need to install unzip from Synaptic or apt-get first in Mythbuntu 8.04.
I copied the *.fw file to /lib/firmware/$kernel_version
Then I ran MythTV Backend setup as usual, and the Kworld was detected fine for both analog and DVB (ATSC), using the stock MythBuntu 8.04 load- no v4l-dvb update necessary, it appears.
The channel scan ran fine, picking up most of my locals, except 2 of them came up with the error "no tables" (where "no signal" would be reported) even though they locked.
I set up the storage directories in a valid, user enabled path, and all the other settings.
I exited, ran mythfilldatabase, which appeared to complete fine, then ran the frontend.
Watch TV produces a blank screen then goes back to the front end menu, just like the Pinnacle 800i did. I don't think ths issue is related to the card type- some bug or config issue with MythBuntu 8.04...
