Smooth DVD ISO Playback? (50hz)

I am very interested in buying the WDTV Live purely for it’s ability to stream DVD ISO files. I have a lot of these backed up (primarily British TV Shows) and I am very fussy about judder and want playback to look identical to the source DVD.

Will the WDTV Live…

-Allow me to select 50hz manually (or Auto-Select if I play a PAL DVD ISO)?

-Play back DVD’s at 50/60fps flawlessly without judder (Hardware decoding)?
