Hello,
I can confirm Andrei Rjeousski's report that tuning does not work with driver
http://mcentral.de/empia/20080804/empia-hardy-generic-i386-latest.deb on kernel
2.6.24-19-generic.
But all is well with driver
http://mcentral.de/empiatech/distris/ubuntu/hardy/empia-2.6.24-16-generic-2_i386.deb
on kernel 2.6.24-16-generic:

With either driver/kernel combination, analog (NTSC) tuning works well.
If I can be of assistance debugging this problem, please let me know.
Thanks,

Hi Marcus,
I've tried to upgrade to the latest em28xx-new version and found that
scanning and tuning is broken. I've then tracked it down to the
following change that breaks scanning.
http://mcentral.de/hg/~mrec/em28xx-new/rev/24208f4a8fe0
This version works correctly:
