Attached is a patch against v4l-dvb repository to add support for
Magic-Pro DMB-TH usb stick. DMB-TH is the HDTV broadcast standard used
in Hong Kong and China.

Timothy,
In order for your patch to be applied to the kernel, a sign-off is required.
Please respond to this email with your sign-off, as described here:
http://linuxtv.org/hg/v4l-dvb/file/tip/README.patches
e) All patches shall have a Developers Certificate of Origin
Also, what software can people use with your device & driver to tune to DMB-TH services?
How do users scan for services?
Dear Michael,
Thanks for your hint on getting the patch accepted. 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.
Regards,
Timothy
