When you get an error like below:

ERROR: This video is DRM protected.
Traceback (most recent call last):
File "/usr/lib/python2.7/site-packages/youtube_dl/YoutubeDL.py", line 793, in extract_info
ie_result = ie.extract(url)
File "/usr/lib/python2.7/site-packages/youtube_dl/extractor/common.py", line 508, in extract
ie_result = self._real_extract(url)
File "/usr/lib/python2.7/site-packages/youtube_dl/extractor/youtube.py", line 1682, in _real_extract
raise ExtractorError('This video is DRM protected.', expected=True)
ExtractorError: This video is DRM protected.

The fix is this:
diff /usr/lib/python2.7/site-packages/youtube_dl/extractor/youtube.py /usr/lib/python2.7/site-packages/youtube_dl/extractor/youtube.py.sav
1681,1682c1681,1682
< #if video_info.get('license_info'):
< # raise ExtractorError('This video is DRM protected.', expected=True)

    if video_info.get('license_info'):
        raise ExtractorError('This video is DRM protected.', expected=True)

Then download seems to work ok
