>>Are you sure you arent just blinking lots and get just the one frame?
As I said , I am a scientist by training, doing 4 years of experiments after my first degree. I know I can make things like propellors appear to slow down by blinking and about setting strobes lights up to get make things appear motionless when really doing 2000rpm.
I will upload the video I have.
Here are some of my thoughts on it.
1. I have facebooked it and no one has responed in recent weeks.
2. I have a 100 or 200 htz tv, but more than than the 50 that terestrial TV is transmitted with. It does does not appear to get recored on the Topfield HDD.
3. This only seems to occur on channel 4/5.
4. My gf has seen them also, but not on any other channel and she like Emmerdale so I suspect that something would have been noticed at other time if it was a TV fault
5. I have seen these mainly in the program itself but also with the TV program advertising you get just before the program restarts.
6. The one I have captured above has a similar advert a few miniutes earlier. But I cannot say this is so for the others.
7. Another one I can remember is for Boots the chemist, and Carslberg think
I can only think of the following options right now.
1. There is some subliminal TV advertising going on
2. My TV is faulty and is extrapolating to 100/200 htz it is somehow saving a frame and accidently mixing it it.
3. The broadcasters are slipping them into the odd frames withing the 100htz so that they are not recorded.
4. Someone is "hacking" the system, like on the film "used cars" where they talk over the presidents speach.
Still thinking of others.
Will post the link and more info as I find it.
