30-sec preview:

HOLY SH*T!!!!!!!!!!!!!!!!!!
this is sooooooooooooooo cool! Thanks so much for this important information! It works yaaoouuuhhhhww

Excellent. i owe you a keg of beer, really. THANKS A LOT!!!

(i dont know if my posts were clear and sufficiently detailed. but your post proves that i dont need to write more details. you have found the MMS-url's and you used them to download the 128k server files with the default method. great job dude. btw, some VERY long AlbumOny tracks (30mins+) seem to pose some problem for the default method if you use the MMS-protocol. no doubt, the MMS-protocol is the preferred one because it surely gives exact/correct download results. in difficult cases (e.g. long tracks!) you need to employ the RTSP:554 protocol ... and dont wonder if everything around you crashes hehe.. The RTSP-protocol is simply not a clean protocol as MMS. Anyway, for a 10mins track, your file should have about 10MB's. If your file is 20MB's, then trash your method (and send me a PM for individual trouble-shooting).)
Code:
mms://stream.zune.net/a4241/e3/109/711/767/at/audio.wma#0;1.000;0;0;1:2
i've examined your given track. it is damn long!! almost 48mins.! wtf?!?!
Here the stats of your file:
Code:
protocol used: RTSP port 554
size: 44,4 MB (46.643.703 Bytes)
track length: 47'56'' (in WMP10)
meta data: A Thousand Suns: The Full Experience / Linkin Park
can be playback'ed by me: yes
can be un'DRMed by me: yes
CRC32: FB0173B6
Can you confirm it (especially the CRC32 code)? (also, see your PM inbox!)
As I found out, here is the url for the 192k track:
Code:
http://download.zune.net/d.php/109/711/767/wu/cache/audio.wmrm10
i get 66,1 MB (69.376.564 Bytes), crc32:43A09392, rename it to *.wma, it is all tagged, 192kpbs. i just cant get it to play with WMP10. [EDIT: 43A09392 re-confirmed on the school computer. download-rate 7.53MB/s!!]

Leaving the AlbumOnly tracks aside, for a normal track (192k WMA) i've compared the http-download-zune downloaded track with the standard download method (DOWNLOAD-button). File sizes are the same, but headers differ. This makes clear that 192k *must* be downloaded thru the DOWNLOAD-button, which will modify the file's header such that it contains some licensing sh*t. oh well. so maybe there's no way that we can get the 192k AlbumOnly tracks to play (or un'DRM).
