I ran up the new version earlier today with my i1 Display LT(after having a b*tch of a time removing the old X-Rite drivers - Windows wouldn't recognise the Argyll drivers as the latest driver).
For others having the same trouble with installing over the X-Rite drivers you have to run Windows policy editor, enable the policy that stops installation of drivers that aren't allowed by policy, then when you plug in your meter windows will abort the auto-install of the X-rite driver (even removing the x-rite drivers from the driver cache and disconnecting the internet didn't stop the auto-install initially). You then disable the policy that you just enabled and then you can manually install the Argyll drivers. More detail here: http://www.ampercent.com/stop-window...atically/5808/
HCFR seems to work fine, but unfortunately it looks like I have drift with my meter as my grayscale has red consistently & significantly high across the different IRE measures, with green & blue almost spot on. I have however just changed my bulb so was expecting to see a fairly random grayscale (unless red on new bulbs is usually higher than used bulbs), and I haven't used my meter for over a year (it has been in an airtight bag with silica & stored in the dark).
Once I work out if I have to replace my meter, I'll do further testing.
The only thing I noticed with HCFR was the occassional French spelling
John, another useful feature for HFCR for those using a HTPC would be for HFCR to automatically press the next chapter button when running thru the grayscale and colour tests. I have some VB code to do something similar that I should be able to port to C++ (even with my basic C++ skills....). This would make it much easier for HTPC users to calibrate.
