I have heard from a couple of folks who have had trouble getting IR learning to work for their universal remote controls after installing Update Rollup 2 for Media Center 2005.
As I described in this blog post, Update Rollup 2 installs an updated set of IR drivers (via KB888795), among other things. Unfortunately, there is a design flaw in the Windows driver installer - it will always writes this registry key anytime a new IR receiver device is enumerated by plug-and-play. The IR rollup package that is installed as a prerequisite of Update Rollup 2 forces such an enumeration when it upgrade the IR drivers. Also, this registry key can be overwritten if you plug in a new IR receiver. Doing so will cause the new device to be enumerated by plug-and-play, and the driver installation overwrites the registry key.
Whenever IR drivers are updated (such as when you install Update Rollup 2), it is necessary to update a registry value to re-enable IR learning in universal remote controls. You can do so by using the following steps to reset the necessary registry value and then rebooting your machine to cause it to take effect:

I have VAIO with PCVA-IR6U IR receiver. I recently upgraded to MCE 2005
Update Rollup 2 and I am seeing that everyday at least once the IR receiver
freezes. Reboot solves the problem. But when the IR receiver freezes, remote
control does not work and if it happens when we are not home, MCE "thinks"
its changing channels but in reality the IR signals are not sent to STBs (I
have two) and thus the actual channel change does not happen. This results in
MCE 'thinking' and thus marking recording as "xyz" on "abc" channel, when in
reality what gets recorded is whatever channel the tuner was tuned to before
IR reciever got froze.
I looked in this blog and downloaded new updates for IR receiver & Oct 06 roll up. This has not helped the situation.
Has anybody seen this? Is there a known solution? How can I debug this
Thanks in advance for suggestions
