DSTV rescanning

If you have an older decoder like the PVR & not an Explora, your programs are interrupted by continuous rescanning as Multichoice are trying to force everyone to buy the newer decoders. I have phoned numerous times & complained but nothing happens !!!! Know quite a few people who had the same problem until they got Explora's & miraculously the rescanning stopped. This is just a money making scheme for Multichoice as you can no longer have dual view & need to buy a decoder for each TV. They need some good competition in S.A., we are being ********** !!!
