Apologies, I missed your original mention of 4TR. For the late notice changes, if the EPG is updated before or during a recording 4TR will catch it, but otherwise it won't. It doesn't currently use CRID as it's a UK Freeview only method I believe but it has been raised to the dev team (check on the 4TR forums). For accurate recording flags, I have padding set to -2 and +5 which has never yet missed the start of ending of a recording. Also, as 4TR/MP allow multiple channels to be recorded (rather than the usual PVR box limitations of 2 simultaneous) at once, if you have a couple of tuners the padding doesn't get in the way of overlapping programmes. As MP allows +15 sec, +30 sec skipping, I can quickly get to or back to the very start of the programme if the padding wasn't ideal. I also have it set to start a programme from 2 mins in, in theory dovetailing with the padding but if the programme started early, it allows me to skip back -1 min say if required as an exception.
For the series link, 4TR stores the details of all recordings and so it knows if something is new or not and this works flawlessly. The downside is that series across channels will can get recorded more than once where descriptions change or episode indicators are ignored by the channel (5 USA being a culprit!), but I don't think Freeview+ handles this either? As 4TR works by text searches it picks up new series or can 'catch' missed but unrecorded episodes out of sequence, which can be useful. I find the conditional setup of schedules in 4TR to be far more flexible than any Freeview+ box I've seen and reminds of my Toppy and MyStuff days a lot.
