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.
