[EX Q]: Had no luck, even with latest firmware, getting the unit to resume any of my audio books. I tried changing the tags on the mp3 files but it did not work. The unit would go into auto shut off and then force you to start your audio book file from the start every time.
[EX A]: Negative

[EX Q]: The sizing of this costume was fairly accurate but it very cheaply made. After only a few wears, the mask and belt both broke. I wouldn't recommend this costume.
[EX A]: Negative

[EX Q]: This item was suppose to contain a digital copy but it only has a Blu-ray and a DVD disk. The digital disk was not included, from the package and from your advertising it was suppose to be included. What happened?
[EX A]:
Positive
