Microsoft Patches “Broadcast Flag”/CGMS-A Issues
Today Microsoft is will a patch to correct the issues seen
in last month’s reported “Broadcast
Flag” issues. In reality, the fix is
for CGMS-A and the official word is still that Media Center doesn’t support the
Broadcast Flag. Last month’s issue propagated from CGMS-A being on the
analog source data that was broadcast by NBC.
The patch changes functionality in Media Center for CGMS-A
on antenna and non-STB configurations where CGMS-A CopyNever (1:1) will be recorded as CopyOnce (1:0) effectively
ending the “Recording Prohibited” messages seen last month. This means if CGMS-A finds its way onto an
OTA broadcast it will always be recorded, but if CGMS-A is set it will be
protected once recorded. If you are
using analog cable (no STB) the same takes places.
For configurations using STBs, this patch doesn’t fix any of
the existing CGMS-A issues which include incorrect and otherwise excessive
CopyNever flags (Sorry Canadians). I’ve
made sure this issue is still on the table at Microsoft, but currently there is
no official fix (other than unplugging your STB). Personally I’d like to see the issue fixed in
the same manor, but that does present issues with content that is supposed to
be CopyNever on an STB. The other option
would be to just disable CGMS-A when Media Center is setup using a Canadian
The patch should be up on Windows Update now (KB950126 - June Cumulative Update) and related download link is posted below.

Update: As noted on
the CE Installer blog this doesn’t cover CableCARD which comes with
CableLabs regulations. With that said, the majority of the issues with
CableCARD could be
software conflicts rather than content flags. If you are having major
issues with CableCARD and Restricted Content messages, please leave a comment
