[HELP] Adding generic DVB-T tuning capabilities

I'm trying to add some generic analog and digital TV capabilities to a program, and I'm having some difficulties with DVB-T.

I'm using the MS Tuner Library, and the MS Video Control ActiveX, and am able to get correct image and audio for most cases... but I'm not able to find how to make an automatic scan function (already done this with the Analog TV but this one seems to be different), don't know how to get the provider and service name, and when I try to view one of the channels the msvidctl control doesn't show the image and crash, but the frequency, transport stream ID and service ID is correct.

Also, couldn't check how to select multiple languages so far (no programs with it right now), nor found anything regarding the Teletext display.

Any help?
