I've now cleaned up the patch to pass checkpatch.pl, and signed it off. I've also attached a second patch against the dvb-apps repository which adds a DMB-TH scan file for Hong Kong. Since the ProHDTV stick contains a DMB-TH decoder (lgs8gl5) onboard, it outputs MPEG-TS to the PC. I've been using mplayer to test the driver. But since I'm using dvb-usb's generic video streaming mechanism, I imagine the driver should be compatible with other DVB software.
