EPG ID in association with TV Channel

[fre-e-trader]

I just received my dp-558 yesterday (rev.6)! :-)

However, in Switzerland we have two very similar spelled tv channels:
SF1 and SFI. Do you see the deferences? ;-)

Now my problem:
I associated an EPG ID to the channels but wrongly twice for the same channel.
How can I remove this association without resetting my player??

Thanx to x3m!
I found the answer @ "Forum/DP-558/little 558 faq"

BUT a feature to remove the assocation directly would be much better/easier!
