Some more data about what streams play (stats for nerds reports these numbers as MB, but I'm pretty sure it means Mb):
On the 3800X running OS version 9.1 (Stick):
20Mb/s 1080@30fps: Video plays back at inconsistent speed, often turns into a cascade of large blocks. Unwatchable
8Mb/s 720@60fps: From watchable with noticeable glitches to perfect depending on the channel. The channels the play perfectly seem to come in closer to 7Mb/s in the Streaming Info section of stats for nerds, channels with glitches go above 8Mb/s, but I don't have a large enough sample to say if that's a coincidence or not
2Mb/s 480@60fps: Plays back perfectly
For now I have the device set to transcode all steams above 6Mb/s, but that's unfortunate because it plays back 10Mb/s H.264 streams perfectly. I'd still prefer a setting where I could set the stick to just always transcode mpeg2. It's a die-roll as to whether an 8Mb/s stream is going to work without glitches, and transcoding a 2Mb/s stream doesn't require many resources on the server.
