hai, this is my story.while surfing net i found some people telling unable to record Airtel DTH programs through Composite Video input to tuner card.Can Composite Video be protected ??? Answer is YES - Macrovision.In good old days VHS tapes were protected from copying.Now it is Composite Video that is protected.I was using Intex tuner card with Composite Video Input from STB ,but i was able to record all programs using ChrisTV.May be Intex is taking account protection flag.Then what are these people telling about recording prohibited ???To find out I bought a new Tv Tuner Card AVerTV Super 009 M733 Aver Media.Installed it and to my surprise ChrisTV only shows Channel 100 [ Demo Ch] of Airtel STB through Composite Input.and only demo channel can be recorded.All other channels are blanked out ....?? First thought --- Man I lost money 🙁So I installed AverTV that came with Tuner card and It shows all channels 🙂 Money not wasted 🙂... wait tried recording ... Is tells recording prohibited ???? 🙁Even Tvideograbber SDK does not show channels only demo channel...So some reverse engineering required >>>>Took my tool IDA Pro [got retail version v6.1 realy good]and analysed driver files of tuner card.To my surprise I found default setting of AverMedia TV Tuner Card is to prohibit recording of Macrovison protected Video and to blank out video if we are not using AverTV to view.Finally I managed to change the default setting and now using ChrisTV and Tvideograbber to view and record videos.Aver Media Tv Tuner Card AVerTV Super 009 M733 is really a good card with no bulky tuners and also it has composite Input.Anyone facing the problem can contact me for solution. 🙂
