I tried the AR on the 2000T. Worked OK on the first two ITV programmes. Completely lost the start of a programme on "Horror". Given that most of my recordings are on minor channels, some serious experimentation is required - or go back to padding. Might try a reset first. 
Horror channel defintely isn't AR.
With my PVR I can separately choose whether to default AR or padding for each channel.
Every channel started of in my personal 'use AR' list but then gets moved over once I had had continual failures.
My core AR channels are BBC TV, ITV, Channel4 group, and Channel 5 group (including Paramount Network).
The exceptions for BBC are being AR are any red button channels and BBC Parliament, for which I use padding.
ITV use to not apply AR to +1 channels, or their more minor channels between Midnight and 6am, but I think they may have expanded their use of AR. Certainly in the last few years the very few that I have tried have recorded very accurately and not according to the published schedule.
Channel 5 use to have a bad reputation for AR. This wasn't entirely fair. Channel 5 were honest in that they used to state that they do not use AR but would continue to reconsider. Eventually they started to use AR and from the start use to work very well compared to BBC, ITV and 4. Unfortunately they had already built a reputation that continued to have adverse posts for at least another 3 years after they started to use AR. They have since gone through a bad patch but I do record from their channels and haven't experienced a bad AR for a very long time, (unlike their sometimes abysmal CRIDs).
No radio channels that I can find appear to use "AR" but this year Radio 4 have started to use an alternative to the more expensive form of AR. Instead of a live feed of adjustments to the EIT p/f (which is what the AR code in PVRs work off) they appear to be using predictive times.
