FOR THE last 6 numbers:
the first 4 numbers are the hour(+4) and minute stream started, for example if it says stream started at 12:30 then the first 4 numbers are 1630.
the last 2 numbers I'm guessing are the exact second stream started, its just a guess.
I tried playing a deleted stream using this theory to play on vlc but got bored(since you have to do it 60 times for every second) and gave up.
Please share if you find anything new. btw I'm using protools
