Burnout Legends feeds its intro movies to one decoder back to back, with
no flush in between. Each new stream opens with a buffering period whose
cpb_removal_delay is 0, which put our reconstructed clock 18 frames back,
so every picture after it was held until the clock caught up, and then
20 came out of one decode. sceMpegAvcDecodeYCbCr converts every picture
a decode reports into the caller's buffer list, which only has room for
one, so mpeg.prx went on through stack garbage and crashed as the title
screen came up.
Such a buffering period now continues from the last access unit instead.
