I installed the 1.06 version of WiiMC, and it did read the DVD this time instead of out right refusing like it did in ver 1.1.0.
however it was very laggy. the sound seemed to go on as normal but the picture just staggered. and on one DVD it also started playing the audio commentary, which would obviously be an extra feature normally.
thanks for the help Joostin. I think i will stick to my normal DVD player for now, as i said before it would have been nice to have all the features working, but i can do without.
I shall probably give the next version a go when its released. but in the meantime i am happy with all the other features available. it has excelent playback for my mpeg's and Avi's etc.
