Try to play all the videos you have available, and catch errors:

This will reliably work, because load() blocks until a decision about
which video to play is made.
We may have to change this (e.g. to allow UAs to asynchronously
fetch and
try each video)
We definitely have to change that! Having load() synchronous would
be a disaster.
I agree! A truly synchronous load() will result in a terrible user
experience as a UA may need to download a significant amount of data
before it knows if a file is playable.
