After reading some docs about mpeg-TS I still have difficulties to realize the effects of loosing TS packets to the macroblocks (16x16 pixels) of the mpeg-2 video. Is there at least one full macroblock in a TS packet? To put my question in other words: If my dvb-t device doesn't get the full stream will this always lead to missing macroblocks or can it yield less obvious loss of quality (like unsharpness)? Does the type of device influence the qualtity of the recieved stream? (Why do devices differ in prices so much?)
