Hello,
I've compiled and installed latest v4l-dvb and dvb-apps, extracted 
xceive firmware, so far so good. Distro is Fedora 11, x64 
(2.6.30.5-43.fc11.x86_64)

Unfortunately scan finds only the first channel:

$ scan  /usr/share/dvb/dvb-t/cz-Praha

if I remove 634000000 from tuning data it works fine on 674000000 but 
again not the subsequent frequencies and so on

Some applications such as vlc that can tune directly work fine (vlc 
dvb://frequency=730000000 :dvb-bandwidth=8 :program=259 etc)

Any workarounds (but merging results from scans per one frequency)?

Thanks
