404 when getting private YouTube video even when logged in with the owner's account using gdata-python-client

If a YouTube video is set as private and I try to fetch it using the gdata Python API a 404 RequestError is raised, even though I have done a programmatic login with the account that owns that video:

from gdata.youtube import service
yt_service = service.YouTubeService(email=my_email,
                                    password=my_password,
                                    client_id=my_client_id,
                                    source=my_source,
                                    developer_key=my_developer_key)
yt_service.ProgrammaticLogin()
yt_service.GetYouTubeVideoEntry(video_id='IcVqemzfyYs')

    204       uri = '%s/%s' % (YOUTUBE_VIDEO_URI, video_id)
--> 205     return self.Get(uri, converter=gdata.youtube.YouTubeVideoEntryFromString)
    206 
    207   def GetYouTubeContactFeed(self, uri=None, username='default'):

RequestError: {'status': 404, 'body': 'Video not found', 'reason': 'Not Found'}

This happens every time, unless I go into my YouTube account (through the YouTube website) and set it public, after that I can set it as private and back to public using the Python API.

Am I missing a step or is there another (or any) way to fetch a YouTube video set as private from the API?

Thanks in advance.

Apparently the YouTube Data API doesn't allow this (yet), so to workaround this I use the GetYouTubeUserFeed method of a YouTubeService instance to obtain a list of all the video entries I need (whether they are private or public):

from gdata.youtube import service
VIDEO_ID = 'IcVqemzfyYs'
yt_service = service.YouTubeService(email=my_email,
                                password=my_password,
                                client_id=my_client_id,
                                source=my_source,
                                developer_key=my_developer_key)
yt_service.ProgrammaticLogin()
userfeed = yt_service.GetYouTubeUserFeed(username=my_email[:my_email.index('@')])
video_entry = reduce(lambda e1, e2: e1 if e1.id.text.endswith(VIDEO_ENTRY) else (e2 if e2.id.text.endswith(VIDEO_ENTRY) else None),
                     userfeed.entry)

Hope this helps anyone having the same problem :)
