This happened again last night.
Recording BBC2 HD from 8 to 9 and had two other programmes to record at 9pm, one on BBC1 HD and the other on C5. I was watching a Blu-ray film and noticed at 9pm the Humax came up with BOOT on the display. Switched back and once it had finished booting I had to manually record both programmes.
Has no-one else had this issue? Normally when I’m watching something on the Humax you get the conflict screen pop up but once the over-run programme has finished it will continue to record. The only common issue is that one of the programmes it was going to record is BBC1 HD.
