I have exactly the same problems. I had channels in jaunty, upgraded to karmic.
In karmic: dvb stopped working (so not only scanning but also recording and watching tv).
I deleted the dvb card, added it again, and then i saw scanning does not work.
I tried nightly builds and karmic builds, event tried compiling latest hg repo from linuxtv (first i thought could be a module problem).
Running:
karmic 64it,
mythtv nightly (actual build: 0.22.0~trunk22354-0ubuntu0~mythbuntu3)
Hauppauge HVR-1300 (cx23880)
Dont know if this is of any use, but when running dvb in kaffeine i get a lot of following lines in /var/log/messages:
......
[ 120.499153] cx88[0]: irq aud [0x1001] dn_risci1* dn_sync*
[ 120.499166] cx88[0]: irq aud [0x1001] dn_risci1* dn_sync*
[ 120.499173] cx88[0]/1: IRQ loop detected, disabling interrupts
