OK, I'm trying to make an AVCHD with a motion menu in MultiAVCHD and it just doesn't seem to work (POWER DVD 10 won't load it). I tried the "relaxed AVCHD" option and a "any Blu-Ray player" option and then created an ISO with ImgBurn. Media Player Classic HC loads it but it only plays the film and not the menu. Could anyone help me with that? Is it gonna work on Blu-Ray players?

I assume you are using multiAVCHD 3 as Adywan suggested. I have never made an AVCHD with a motion menu and do not use any of those programs, so I cannot really help, other than to suggest you try the strict AVCHD profile. The only way to know is to burn and see; if not on your player, then on someone else's. Blu-ray players being fussy with AVCHDs is unfortunately rather common.

Now you understand why I recommended 1-pass turbo. :-) 2-pass VHQ took me at least four days i.e. 96 hours. As I said before, the developer of multiAVCHD himself uses 1-pass turbo. If you must perform a second pass, use 2 -pass fast, but it is a waste of time in my opinion. You might also try Ripbot, but I think multiAVCHD 3 yields greater compatibility.
