I know I got two maths degrees but reading he doesn't mean that since that would be wrong since any future version above 1.03.11 in the 3 series we can assume won't have portal issues with other 3 series ... only af123 would know. As we all know but some are in denial is that the 3 series is an improvement and runs on a different browser which presents a newer BBC iPlayer. The portal was thus changed which requires old custom portals to be removed for the new one to work correctly.
Its that if you have previously installed the 2 series and with the custom portal software then some tidying up of the previous custom software is required, if installed over the top. Personally ideally the upgrade (oh yes this concept you have debated with me previously whether 3 is greater than 2) af123 should ideally put something in it to remove the old custom portals. Another instruction on the threads is to remove all custom firmware then upgraded this avoids this issue.
