In this case you have wrong url. It's mixed HTTP and RTMP url and filter doesn't what to do. You should use HttpUrl class for HTTP url and RtmpUrl class for RTMP url.They both suffer from "No URL" syndrome.
Log has a few that don't work from both TVNZ and TV3nz.
Pretty sure the problems are with their sites, nothing you can do about it.
Overall most stuff works, just an occasional "No URL".
It's known and fixed problem. Download new version of MP Url Source Filter or wait for new OV version.I mentioned a program missing the last minute after downloading. This is not a problem with these sites but an overall problem with ONLINE VIDEOS.
It happens quite often to files from all sites.
