The HLS stream in the m3u8 file is copy protected so cant be downloaded directly. So using the DVR is the correct way to go.
The logs show that you have used the m3u8 link for the DVR. The DVR requires the hosting page as the URL.
In this case the hosting page is in a iframe on the page. For example the page http://meloman.ru/concert/aleksej-kozlov-80-let-so-dnya-rozhdeniyayubilejnyj-koncert/#webcast has the hosting page for the player within an iframe at the following page http://player.meloman.facecast.net/15-10-26-19-00-KZCH/.
We will add facecast.net as a known iframe hosting page in a later release so this detection happens automatically. But in the mean time you will need to view the page source and find the url of the iframe hosting the video and use that in the DVR.
