If this has already been answered sorry but I am catching up on the -dev list after a few days of ignoring it.. Are you using hte DVB drivers for starters? (I have to assume you are if you are scaning).. Can you tune to some multiplexes where you know channels are and see if you can find an VCTs (i.e. data on PID 0x1FFB).. Some cable systems don't send VCTs from what I have gathered from the list and when the scaning app gets no meta data it just bails out and gives up.. I need to change this, but I need to know if you are getting VCTs very slowly, or if they are just not present at all.. > I was wondering if anybody knows about this problem and/or may be > working on it.

I will be glad to assist you, but chances are I will be digging into this for the next few days since my 5th gen Air2PC should be here tomorrow and I want to make it work with Cable as well as 8VSB since thats what is specd out to do..
