Most notably, Apache replies

Content-Length: 3576576672
Content-Range: bytes 0-3576576671/3576576672

and tvheadend replies

Content-Length: 3576576672
Content-Range: bytes 0-3576576671/-718390624

Notice the /-718390624 part, which then leads to really weird byte range for the seek command Range: bytes=4088415515507163136- , although Content-Length is correct but it seems vlc does not care about that one.
