This issue should be fixed in youtube-dl 2012.01.08b. You can update youtube-dl with youtube-dl.py --update. Note that the switch from bytes (or even worse, mixed strings-bytes, "encodingless strings") is a huge change and may not be correctly applied in every IE. Please do open a new bug if this or a similar error occurs again.
