I fetched and compiled fresh ffmpeg ([11634]) and tried ffplay with
several problematic recordings. In all cases ffplay dumps valid
resolution. I've attached one example where is relevant parts of data
from mytharchive, streaminfo.xml and ffplay.

This is just guessing, but would it be possible to advance the position
from where the stream info is fetched? So that if we don't receive valid
info, try 3-5 times and each time go bit further? If the beginning of
the stream is somehow corrupted and working values can be fetched little
bit further..
