As I said it's my pleasure!! You are so welcome!!

luckily, The playback vids are using HTTP for streaming!! Use a free software like StreamTransport for detecting and downloading them!! Also you can track packets and find the playlist file via Coojah!!
For example:

http://vdd.player.cntv.cn/liveback.php?channel=cctvmusic&starttime=201203190735&endtime=201203190838

Also if you notice at links, you will find out there is a good help to figure out next links!! Red highlighted ones!! Each link, contains 5min! So, 5*12=60 !! You just need to edit them to get any vids you like!!

if there is any other little help that I can do, let me know!!

Good Luck, friend!!
