Instead of using just vlc, try using streamlink (+ streamlink-plugin-dashdrm if you want multi audio) to parse the stream and pass to vlc to play, you'll get the full resolution then
I've also done a quick scan. starting from 0 this time. Other channel numbers that appears to be valid:
001 live stream
003 tnt sports 3
004 tnt sports 4
011 eurosport 1
013 ?
019 sky nature
028 M+ (motorsport?)
051 ?
052 ?
The mix of channels...
I concur with the others comment to not use a browser to view dash streams. On a PC you can always use vlc if not drm protected, and streamlink + streamlin-plugin-dashdrm + vlc if drm protected - which works cross platform (*nix/windows)
No keys or kid needed

The number after TVD can be changed randomly to get other channels. If you can get more of them, drop them here with their titles.
Unfortunately, as the others have said, its not that simple. Perfecttv didn't generate this MPD, they either copied it and re-served it, or they are proxying it on the fly. The MPD is dynamic, so u need the live version to play the stream...
