Update: Manual install instructions && installers for users on stock AsusWRT have been posted
Update: v8.4 aswell (there was an additional bug report open on the github page I missed)
AppDB - 12003F was not functioning as expected
@TicoMan Are you sure the Sony Download was not actually going into Web Surfing which is above video streaming.
That is the only reason video streaming should/would be choking.
(You have to really observe the rates next to the pie charts for a complete picture).
You have many options to choose experiment with
1) If your game download is going into web surfing then to remove it from that section, as a very aggressive rule you can take all TCP traffic from remote ports 80,443 but only dealing with your game consoles CIDR range and stick it into "Game Transferring"
2) Or slightly less aggressive, you can take all TCP traffic from remote ports 80,443 with a current traffic mark of (13**** or 14****) but only dealing with your game consoles CIDR range and stick it into "Game Transferring".
Not sure which mark your game download was detected as. Do some more investigation if you need 13****, 14****, both, or simply the aggressive rule which swallows ALL the marks.
3) You can also bump the guaranteed rate higher for video streaming, so the new minimum guaranteed rate causes no buffering irreguardless what is happening elsewhere by taking some bandwidth away from other categories.
4) You can put Video Streaming above Web Surfing
There's lots of options at your disposal .... experiment
Typical traffic on ports and protocols was explained, and should be apparent when studying tracked connections. You then can spot more patterns with MARK for specific use cases.

Also if you ONLY have one gaming device active at a time.
You can simply stick all its traffic (Game + Game Downloads + ALL) into "Gaming" and place "Gaming" 2nd from bottom. Since it is only one device in the category, the console should be smart enough to PAUSE game transfers while it is actively playing online. Even though you placed it 2nd to the bottom, until it exceeds its guaranteed bandwidth it will still have first dibs on the network access.

@TicoMan
Report back, game transfers showing up in "Web Surfing" was your issue.
I can cook up another optional gaming rule to make more assumptions and stick MORE stuff into "Game Transfers"
