Guys this is a very GENERIC blindscan function screen, based on the blindscan plugin, modified to be integrated into the OpenATV system. It utilizes external binaries on some blindscan-capable tuners, provided these are present in the firmware either directly from the tuner manufacturers, either from the receiver manufacturers and in that case they are closed sourced and encrypted to work on that receiver only!
Even though the scan results, especially with Silicon tuners are quite satisfactory, this approach is based on incomplete coding. Proper blindscan is a function that has to be built in the Scan Setup screens as a search type. For Silicon tuners only DMM has this implemented correctly and of course they keep this coding as a well kept precious secret.
Honestly, all manufacturers that use Silicon Labs tuners are to blame here. They are totally responsible for not activating blindscan on their boxes. In Octagon's case it's even more blatantly apparent that they use the Blindscan feature to promote their new receiver's sales, although SF4008 is more than capable of hardware blindscanning!
