This is [ceskatelevize] ... why youtube-dl doesn't recognize it? #5482

On other URLs of the Czech TV (e.g., http://www.ceskatelevize.cz/ivysilani/1096911352-objektiv/210411030401003/obsah/127997-ukrajina-lvov/ ) youtube-dl properly recognizes that it is a Czech TV and uses appropriate settings ([CeskaTelevize]), but not here:

You can look into youtube_dl/extractor/ceskatelevize.py and see for yourself: this URL format is simply not recognised.

Adapting the extractor to handle this case is easy, but there is a problem: on /ct24/ pages the web player is configured to play back a fixed time slice of a larger video. I'm not sure what is the best way to handle this in youtube-dl. My WIP code emits a warning and downloads the whole video. One could pass -ss and -t to ffmpeg instead.

Works fine with latest version (2016.05.16).
