I've just had something similar with Primeval and Thank God You're Here.
I've Emailed Humax Support with the following details - perhaps if they investigate and find it is the ITV1 metadata causing the problem they can put pressure on ITV1 to get their metadata in order:
I have been using Accurate Recording and Series Link on Version 1.00.21 since 14/1/2008 and have hit my first real problem - 2 TV programmes have disappeared from the Scheduled Recordings list having successfully recorded. They are Primeval and Thank God You're Here. Here are the details:
Among the many recordings in the list (I had about 23, 21 are AR/SL, and the other two are weekly timers for non-SL programmes) I always have the following programmes set for Saturdays (the times vary, the times shown are for Sat 9/2/2008):
1700 - 1800 BBC News 24 (weekly timer as this programme has no Series Link metadata).
1850 - 1920 ITV1 Harry Hill's TV Burp (AR/SL).
1920 - 2020 ITV1 Primeval (AR/SL).
2150 - 2240 ITV1 Thank God Your'e Here (AR/SL).
I've not had any problems with these programmes each week - until this weekend just gone. Normally, when checking the schedule after the programmes have been broadcast, the date and time still stay the same in the list until Thursday/Friday the following week when ITV1 get round to flagging the coming weekend's editions as Series Linked. However, having checked the schedule this Sunday (10/2/2008), I found that Harry Hill is in the schedule still with Saturday's date (9/2/2008) but Primeval and Thank God You're Here have vanished.
The time scale of my actions on Saturday was as follows:
1730 I brought the machine out of "standby". It was in "semi-standby" as it was recording BBC News 24. The box was also tuned to BBC News 24 for viewing.
1731 I selected BBC News 24 from the Recorded Programmes list (to view the main news broadcast at 17:00).
1805 I finished viewing the recorded news. Box left on BBC News 24.
1830 I selected another previously recorded programme to view (recorded the previous day). I used "ad skip" used to skip over adverts in the programme.
1930 I selected Harry Hill's TV Burp to view as it had finished about 10 minutes previously. I used "ad skip" used to skip over adverts in the programme.
2000 I selected another recorded programme to view (recorded the previous day).
2030 I selected Primeval to view as it had finished about 10 minutes previously. I used "ad skip" used to skip over adverts in the programme.
2130 I selected another recorded programme to view (recorded the previous day).
2230 I put the box into standby (while it was still recording Thank God You're Here).
I use the Crystal Palace muxes for the Humax. Signal strength is 69%, signal quality is 100%.
