has anyone got any experience of this kind of issue?

i tried to record a documentary off BBC 4 late night on our freeview set up at the college i work at. we have a Panasonic freeview box and a Panny E55 for digital recordings - useful for recording educational stuff. it's all connected via a scart, which allows the Panasonic Freeview box to control the recorder via the programmable EPG. i've used this setup in the past to record from E4 and other channels on the list with no problems. however, the recording from BBC 4 has recorded with the red 'data screen' overlaying it, completely obscuring the TV picture. what's going on?

just to clarify, this is the 'data screen' that appears on BBC 4 when it isnt broadcasting - which is most of the day, apart from 7pm to about 2pm. it has a little message at the bottom that says "if you can see the TV picture behind this message, please tune out, them in again to this channel" which i'm is fine if youre there, but what about timer recordings? as it is i've got a disc now with 2 hours of this message and the sound of the documentary. what a load of crap!

this is clearly a BBC4 broadcast issue, but i've yet to find a customer contact for bbc 4 so if anyone has a customer services number, then please let me know. cheers.

and if anyone knows how i can avoid this happening in the future, apart from not recording from bbc 4, that would be cool too. thanks
