The Shield TV is 32bit whereas the Pro is 64bit.

I'm currently testing the Shield TV but Kodi is crashing when playing 4K movies and you try and do something else like open bookmarks for them to be created.

How strange that the two devices with the same SoC are running such different Android builds. You'd kind of think they'd have struck to a single build for the range?  Is this a RAM difference do you think?  Does 64 bit code use more RAM than 32 bit?

(Presumably the previous versions of the Shield TV and Shield TV Pro were the same flavour - as they differed only in the presence or absence of 500GB of storage? Then the later Shield TV non-Pro was a bit smaller and lost a few facilities compared to the original launch version, whilst the Pro remained the same, based on the launch version?)
