I have some problems with converting WMV file into AVI. The problem is because file needs some license from internet. So when I open that WMV video file in WMP, it connects to internet and receive license (I have license - login and password). But I want to convert into avi or delete that ask for license. How can I do that? I try to use ASF Tool but there is no place to put that login and password
Thanks for help and sorry if something is unclear, English is not my first language :)

hm interesting topic
but i guess there is no legal way to convert drm protected wmv files into another format
afaik there was once a tool which could crack the old m$' protection system, but this will not work for newer files i guess
is the file encoded with wm9?

how to check is it wm9?play the file with mplayer2.exe (its in the wmp9 folder) go to file -> properties or so
if "wmvideo decoder dmo" is used for decoding than it is wm9, if "windows media video decoder" is used some older version

Same question (http://forum.doom9.org/showthread.php?s=&threadid=67411) from less than a week ago. Might I reccommend the Search (http://forum.doom9.org/search.php?s=) button in the future? ;)

Any app trying to open such files (with one of the wm source filters) has to have a licence from MS. Since it is free, one could request a lib, link it to his converter and transmux/code it into anything else through directshow.

I am having a similar problem. I bought this Microsoft "Do Amazing Things" DVD for a few bucks because it has HD WM9 versions of the BMW Films on it. Cool, right?
So I try to play the file. "Acquiring License" appears on the WMP status bar, and a window pops up. That window leads to a Microsoft.com 404 page-not-found! Awesome. Looks like MS has stopped supporting the content on this DVD already, leaving me no option but to use some sort of crack to watch this stuff.
My thought would be you could develop a web page which fakes the license stuff. From the looks of the dialog, my guess is that the web page passes back some key to the player. If you could a) get the player to go to your website instead of the one the file directs it to (by modifying the windows HOSTS file, maybe?) then b) get that website to make the player think you have a license, you'd be set. Not that it's an easy thing to do, of course...

Good! You should return the movie where you bought it :)

Ha! I bought it directly from Microsoft for $2.99. It's almost not worth the effort of returning it. It's certainly not worth the effort of bypassing the license acquisition... or is it? :sly:

You could sue Microsoft for 1 000 000$ for selling things that don't work. I could do the same with Windows :D

The lib isn't free, you must pay verisign for the digital signiture and MS will only give you the lib if you're a valid entity (i.e. a registered company).
And to top this off, if they ever hear of anything like a transcoding application, they will invalidate your application for any future decoding (I guess they can somehow do this as part of their DRM) and then maybe sue you for good measure.
I am in the process of talks with microsoft about playing DRM content in ZP and it certainly isn't easy to do if you're not a lawyer.

player developers should get money from m$ for supporting (= helping spreading) their technology

You have to have one for digitally signed letters, ssh on webservers and such, but I'm not sure which one MS wants if there are different kind of these.And to top this off, if they ever hear of anything like a transcoding application, they will invalidate your application for any future decoding (I guess they can somehow do this as part of their DRM) and then maybe sue you for good measure.That's a problem definitely, but I wouldn't need to release the application itself, just the endresult on some p2p network, not that I ever wanted to or had time for such :D But others with a little dshow programming experience at least (and money :)) could do this as well.I am in the process of talks with microsoft about playing DRM content in ZP and it certainly isn't easy to do if you're not a lawyer.I've tried it too once... Now I just hope DRM will die because nobody will want to support it.

Hi,
is it possible to open DRM protected WMV9 HDTV files
in Graphedit somehow ?
Somebody wrote you can use the Matroska muxer for this and then save
the output via filewriter into a matroska format !
When I try to open any DRM protected WMV9 file in graphedit,
it says it can´t open it...
Is there any trick to decompress any DRM protected WMV9 file
via graphedit into another format and save it to disk
without the DRM ?
I just bought the Coral Reef HDTV DVD and I want to extract a few
clips from it and recode it to some AVI files and want to
play with them.
Any possibilities to do this ?
P.S: I don´t want to copy the whole disk, just need
a few sequences for some editing and want to try to
edit HDTV content.
Thanks !
Regards, Harti.

In short: no way.

Somebody posted, that it works by using the new matroska
directshow muxer and then mux it somehow first via graphedit into
a MKV container and then from thereon remux into AVI again via graphedit, but I don´t find the posting anymore on this board.
But I have read your post Gabbest, where you said, that you would
have to require a library from Microsoft to decode the DRM stuff
first . SO your Mediaplayer Classic also can not yet play DRM protected WMV9 files.. Will you get that Lib from M$ ?
Another idea would be to patch somehow the Windows Mediaplayer 9
so it could play WMV9 files without the license !
Does somebody know, if this has been done ?
Or is inside the license key also the decryption key for the file ?
I had premilary success results with using HyperCam capture tool
and capture the output of WindowsMediaPlayer9 to a file this way,
but the resultant AVi file from the DRM protected WMVHD file was quite a bit with framelosses, as the HyperCam application can not write all the frames fast enough to HD.
There is a faster utility like this from www.fraps.com
but I have not yet tried the full version.
Also it seems it is limited to 640x480 res only but it is definately
much faster than the HyperCam program !
When I tried to capture with it to AVI the Scooby-Doo DRM protected WMVHD trailer from the wmvhd.com site I got a pretty good AVI framerate, but the bitmap planes were out of order, cause the free version only supports 640x480 res !
I guess we need a better DirectX based capture program for Windows Mediaplayer9.
Thanks !
Regards, harti.

BTW, how am I supposed to play any of these beautiful DRM protected contents on a PC that has >> no internet connection << ?
Example from practice: Some of the latest published WMV-HD trailers from MS are protected. Now, my internet PC is way too slow to play these files. My multimedia'n'working machine has no internet connection (best possible safety exept from not enpowering it at all). Now ... dead road problem, or what?
Big LOL

sure, you can ship the end-result... but how can you know for a fact that microsoft doesn't watermark the video stream (or bit stream) with your stub identifier... I wouldn't put it past them.
Didée:
The logics behind this is "you downloaded them from the internet, so you should have an internet connection".
Some of the newer WMV9-HD-DVDs have DRM which doesn't require an internet connection.

Well, reencoding it at the same bitrate wouldn't hurn the quality that much :) But I think it could be done without having the lib too, if wmp or any other player (realplayer had some kind of drm license, but I may be wrong and it was their own drm...) uses the wmv/wma decoders then we would just have to over-register them with our fake decoders and output the bitstream into matroska. (edit: just checked wmp and realplayer, they don't seem to play wmv through directshow... but maybe another will in the future, Blight: what's your progress on filling those licensing papers? :D)

Gabest:
Got both certificates (tons of paperwork for the object cert) and sent microsoft the signed contracts. Once I get confirmation that they got it, I'll send them the signed object and hopefully get my stub.
The thing is, shouldn't WMP9 have this stub? What's preventing someone from extracting it from WMP9... Would microsoft void their own key on millions of systems?
