You have mentioned that the FTA channels in sun dth are of MPEG-4 format, if that is the case, will i be able to view the channels, if i purchase the MPEG-4 format STB.
It is possible to receive FTA channels on SUN DIRECT by MPEG-4 STB, but it's risky to invest in MPEG-4 STB's as they are more costly and SUN DTH will not always telecast channels in FTA, once channel testing phase is over, they encrypt that channel
