I don't know if this is the best place to ask this question but here goes.

Why do Canal Satellite and TPS use both Mediaguard 2 and TPS crypt (Viaccess 1) on most of their channels? I thought Canal Satellite's subscribers had to have a Mediaguard receiver and point the dish at 19°E while TPS's used a Viaccess CA receiver pointed at 13°E. Presumably those who want both packages have to get a receiver with both CA systems and a dual LNB. If two CA's are used the channel must be doubling its encryption costs especially if they're as expensive as Sky's charges.
 
In most cases, providers who simulcrypt do so due to either inheriting a viewing audience or because they have upgraded their encryption, but a large proportion of their audience still have receivers only capable of decrypting the earlier version.
