The IOBOUND error messages come from the ThreadedFileWriter when things
are being put in faster then they are being written out.
If the main recorder loop was blocked trying to write to the recorded
table, then it wasn't capturing any data so there wasn't anything to
write. When the ivtv buffer filled up and the mpegrecorder hadn't
read any data yet, the ivtv driver started dropping data.
