The VSH's video player outputs sound through vshbridge.prx, which imports
sceVaudio under its driver name, so every sceVaudioOutputBlocking went
nowhere. Register the same functions as sceVaudio_driver. The player
reserves its channel with sceVaudioChReserveBuffering, which in vaudio.prx
is sceVaudioChReserve with a flag set; treat it as that.
It also polls sceDisplay_driver_996881D2 through vshbridge.prx, and skips
setting up its picture output when it's 0. display_02g.prx's init sets
that from the LCD panel type in IdStorage (0x0103000B for type 1,
0x0103020F for type 2), so it's never 0 on a PSP.
