I've had no luck with CIR drivers really. Just got my replacement so will investigate in next few days. It appears AMD users have more luck. I did a quick test last nite with VLC player and no drivers installed, it didn't appear to recognise any remote commands.
The IDT driver posted above has power management on, so it "pops". I will see if this can be disabled in the registry anywhere. There is no control panel app for it. Else I will try the modified drivers posted earlier.
I will try dannyres, thanks for heads up. Edit: Awesome, most buttons now function with the remote! DVD and QP don't (don't have QP installed anyway), nor do the Media Centre specific ones as is to be expected. Not all work OOTB with VLC player, probably need to be setup. Also, seek back didn't appear to work with Media Player, but only test with old version 9.
Regarding the "pop", it might not have defaulted to doing this, but might have been because I added the stereomix registry info, which appears to enable power saving modes. I changed some of those values and it appears to have stopped.
I'm having slower than expected drive performance when navigating using explorer. It appears to be better without Intel Matrix driver installed. Sometimes there is a slight, perhaps 0.5 sec delay before opening a folder, or going "back". I've tried on a slower XP latop and it's instant in all cases. In addition, sometimes it is instant on my machine. For eg, if you access the windows folder, then back, the windows, back and repeat, sometimes it will be instant, other times there will be the pause. It's quite annoying and really shouldn't be there IMO. I might have tweaked something by mistake. Anyone notice this? You will need to go back and forth several times at least. By comparison, the slower laptop loads the windows folder instantly and it has more files in it than mine. I'm running a fresh install of XP, nothing much else except the drivers. I've disabled powermizer incase that was to blame, but it's not.

I've determined that Intel matrix contoller is not to blame for slow explorer navigation - it's the windows sounds. Remove the "start navigation" sound and all is good. Even if you asign this sound to "end navigation" it still causes slowdown at times. I checked this on the other laptop with XP home, and it did not have a "start navigation" only "end navigation". Even when end is assigned a sound, that laptop did not slow down at all. I would put this down to a driver/hardware issue. Both the dv6 and modified driver perform in the same manner.
The dv6 drivers default to powersaving, causing a "pop" noise to turn on/off the speakers. To disable this, search the registry for "AllowHpOnNonSupportingPin" and keep searching until you are in CurrentControlSet (NOT CurrentControlSet001 or otherwise).
Change the values of CPL_MaySwitchExtAmpPowerState and CPL_SaveExtraPower both from 1 to 0.
