For all Microsoft fans :) Blight (developer of Zoom Player) is writing the following in the avsforum:
A cry for help! Microsoft, DRM and WMV
Several users have contacted me saying WMV playback is not working with several new titles and web downloads.
For a week I've been trying to figure out what is wrong and with the help of one of their content developers we come to the conclusion that the DRM library I originally licensed from microsoft doesn't give my application (Zoom Player) the Application Security level required to play this new content.
So I mail Microsoft's "Microsoft Windows Digital Media Division" asking what I need to do to get a high Application Security level so that my player could support their format.
The first reply was that they are not tech-support. I insisted that I wasn't asking for tech support but rather desired an updated library with higher security so that all WMV content could be played.
Here is the reply I received:
"Hello Yaron,
We do have a new Format SDK 9.0/9.5 license agreement that does offer a higher level DRM Stub.lib file. However in order to obtain this stub.lib file you will need to do the following:
1. You will need to execute a new Format SDK 9.0/9.5 license agreement with us.
2. In order to obtain the 2000 level stub.lib file, we will be assessing a fee of $10,000 per stub.lib
For your reference, I have attached the New Format SDK 9.0/9.5 license agreement. Please feel free to review this agreement and inquire us about any questions or concerns you may have."
What am I to do here? We are a small software developer?
I know some Microsoft personal invovled in WMV are reading these pages... Is this the new microsoft standing on PC-based WMV playback?
(...)
I'm not actually sure there are any security changes involved...
From what I can tell, the only difference is that the original DRM library we authors received had a security level of 1000 (or maybe even security level 100, it's unclear as I don't think the application security level was mentioned in the original license I signed). And now (by default?), the windows media encoder encodes at security level 2000. Most content creators aren't even aware of this as anything encoded plays for them in Windows Media Player just fine.
Now to get the 2000 security level, you need to pay $10,000 and have microsoft inspect your application.
To get the original code, I had to get two digital security certificates, which required me to get a lot of paperwork from our accountant and other company info so microsoft can be assured that we are not some fly by night operation.
Now, what scares me is, even if we paid the $10,000, tomorrow microsoft can released a new version of their encoder and set the default security level to 3000 and once more all new content won't be accessible and most content creators won't know any different.
I'm not trying to raise the DRM discussion, it's been done before in a lot of details. All I want is to get it to work...
