DivX Plus HD MKV, H.264, AAC/MP3/AC3. Plus creates files up to 1920x1080 and also avi's. Perian does suggest another player... something like niceplayer? but I have 3 others so I don't need it. The interface of version 9 is much better than the previous one with a drop down menu showing the above. Also the conversion speed is much faster. I converted 2 this morning.
I have just taken time out to play a QT movie in the DivX player with no problem.
I am very pleased with 9 but I will leave perian installed for now. I don't anticipate anything untoward with leopard but if I do, I will let you know.
Thanks for the reply, jaybass
