Trying to watch a Chip & Dale Christmas short and it won't play on my Z9X w/ 6.4.42 FW, screen goes black maybe 30 seconds then I just get kicked back out to Media Center. Is there anything that stands out in the mediainfo as to why playback isn't happening?

And since I have no idea how the hell the previous issue got fixed, I'm not sure how this will fix itself. I'll reboot everything tonight and try again tomorrow, maybe that works. In the meantime, it's a pretty standard file based on the MediaInfo, right? I don't see any strange codecs or settings that should throw it off.
