My Mio+ has TNAP 3.2 as supplied by Titanium. I have always used NTP for time control. Since receiving my Edision, I have had to do a manual date/time update a couple times using NTP, but I believe only after doing restarts so that is to be expected. I normally leave my Edision powered at all times, especially if I have timers programmed.
I did a couple test recordings last night for 30 seconds and 1 hour. Both tests worked perfectly. I did change the "After event" setting to do nothing. I thought maybe auto means it automatically stops recording if it senses end of, loss or no signal. I prefer it simply to record the programmed time and stop.
