and they get success but problem in samsung HD stb causes and thats why they change format but very soon picture will be clear. [mpeg2 tp can be scan mpeg4 channels hence it will create some additional space by changing some channels in mpeg4 but tp remain same in mpeg2]i think they r checking by putting Mpeg4 channel in to mpeg2 tp,because old stb can not support/scan mpeg4 tp so they r doing this.
