[QUOTE="mm1352000, post: 1027371, member: 82144"] Frankly, I wouldn't recommend using a PC TV tuner strength/quality readings as a reference... however, if you only care about "ball-park" accuracy then I guess it would suffice at a push. From a code perspective I would advise[B] against[/B] hooking into the DirectShow graph. We don't expose it directly so you'd have to modify the TV library (refer to TvCardDvbBase.cs).
