If anyone has LLVJ-19 playing well on an Apple iPad, I would also be interested in the details of any trans-code necessary.
So far I have tried two conversions of LL-19 segments. First was just letting iTunes do it, a new menu option in iTunes 9.1 is to create an iPad version.
I also used handbrake with the settings discussed in this thread on their forum. http://forum.handbrake.fr/viewtopic.php?f=7&t=16303
Both look great on the iPad. iTunes makes a new copy of the file so you end up with two showing, but there is no obvious indication of which is which when you sync the iPad. Using handbrake I created a new folder so I had a little more control.
Not sure yet which is faster or more efficient.
