Bro Q3 quad core only has 8GB flash minus the OS and App partition, left only 4GB free space. That is the,reason you're unable to download movies 4GB and above.

This is the reason we advise our customer to buy Q16 instead.

think i mentioned this before.

that does not work for q5ii. think same for q5iii or q3.

after specifying path to usb ext hdd, it appears to dwnld n play but the speed/seeds/peers very quickly goes to zero.

somewhere in this thread, i remember another user while exchanging comments with me said he tried with ext sd card - doesn't work as well.

reading about this issue with other devices in other forums, it seems popcorn dwnld/play only works with the flash, not ext memory.

if u find otherwise, i'll be surprised.

i actually tried ext hdd on q16, same result, won't work. works only with flash memory. but for q16, that is good enough for almost everything popcorn has to offer.
