How did you generate your channels.conf ? Ive started working on a new app called utuner (http://gna.org/projects/utuner) it attempts to generate the initial tuning data that is input to scan, similar to w_scan. If you want to give it a try id appreciate some feedback, its only a few weeks old and i dont think anyone except me has tried it. It uses a frequency table to isolate what frequency bands to test, it works by looking for the shoulders of firstly the carrier and then the lock band. Example of usage is dtv-scan -t <some path>/channels/Australia.center generated-initial-tuning-data If you dont have a frequency table it will scan the entire spectrum that the card can go to, it uses a step of 500kHz to detect a carrier and a card might have a range of 500MHz, so it means it has to take about 2500 samples this way, currently it takes multiple samples, one every 500ms or so and or's them to overcome inconsistent signals. This means it can take 2 hours to do a complete scan, this is a long time, but its faster than the week it took me to work it out... and it can be greatly reduced by having a frequency table of authorized broadcast bands (such as i have done for australia) for different regions/countries. There are a few other utilities that i have used for testing my card in there as well.
