Nico-nico recording help needed!! Options

[LLQ]

Do As Infinity has quite a number of live on nico-nico. As such, there should be quite a number of people here who is able to record live streaming from nico-nico. There is another of my favourite band, STEREOPONY who will also be having live streaming of their concert at sakura con on nico-nico on 6th/7th of april (depending on which part of the world you are in), but the problem is i wont be free at the timing and i also do not know how to do it. thus i'm wondering if anyone here is able to record the streaming and upload it? any help would be much appreciated!! thx in advance!!
wonder if there's any stereopony's fan here too?
