Any suggestions on what the best way to fix this is?

Maybe the packetizer should count the number of bytes dropped since the last
sync when trying to sync, and throw an error if it hasn't been able to find a
sync for N bytes (and on receiving EOS if it hasn't found a single sync yet)?

Maybe it should throw an error if the file doesn't start with a clean sync (or
is that too much of an assumption to make?)?
