[QUOTE="Waterhond, post: 75097, member: 1200"] Actually what you're seeing in this instance might be NTSC to PAL transcoding and multiple digital compression and re-encoding artifacts. Some of the live stuff goes through up to 5 "hops" to satellite and back. I used to work at M-net/ DSTV and depending on where the transcoding to PAL takes place in the chain the effect can be very bad. M-net has their own very good transcoders and when they have a direct feed (1 hop) the results are very good - Due to shared and combined contracts on some events however, the transcoding sometimes may happen somewhere in Europe using some old less than optimal transcoder from decades ago! The re-encoding also causes a lot of the ghosting and blocking. [/QUOTE]
