Hi

thank you very much for your patch. But would you update your patch, because there's new version patch from
Darron Broad http://dev.kewl.org/hauppauge/v4l-dvb-hg-2007-12-09.diff
with very important diseqc-fix. I mean the DCL-fix (dynamic current limit for ISL6421)

Also, I can't lock the dvb-s2 channels, only dvb-s channels I can lock
