I am not new to Mythbuntu but had to do a new install due to a motherboard melt down. I am running the following:
Asus Striker II Motherboard
Full water cooling cpu, gpu's, hard disks etc...
Dual Nvidia 7800 GTs in SLI
Haupaugge PVR-150
46" Sony DVI HD Monitor
Cable company box by General Instrument
Optical audio to 5.1 Amp
775 socket P4 3.2 32bit CPU (I know, I know, saving up for a quad core)
I am on Ubuntu 9.04
Dual 1TB SATA drives
Raptor 160gig primary drive
700W silent power

Everything above minus the new motherboard and the second Nvidia to run SLI is as it was in the previous build. I was running a full mythbuntu system. I liked it but I was just not used to the differences between Ubuntu an Mythbuntu and wanted to go back to the Ubuntu with Myth on top option.

Everything is working minus the TV. The card is found with this info:
~$ dmesg | grep -i ivtv

I see the card in the myth backend when I set-up the capture card. When I go to the input connections and try to 'connect source to input' and add channels on composite 1 or 2 or s-video 1 or 2 the backend immediately crashes and I get a 'Would you like to run mythfilldatabase?' pop up.

Some notes of possible interest. I do not get a crash when I select tuner 1 but I also only find a couple of static channels out of the 100+ I used to get.

I also tried to set-up tuner 24 and 32 and they crash differently in that one crashes on tuner 1 and the other seems to crash randomly. At any rate I cant get any TV.

Any help would be very appreciated!!
