Not to my knowledge mate but i would also love to here from others if they know of such a plugin.
I wanted something like this since the early DM800 days.
Ferret
just got my Duo and wow, it's cool. and best of all i have found a series link thing that works.
i'm using Gigant Image.
1 setup & download epg data with EPGImport
2 download new plugin AUTOTIMER
3 goto to plugins
4 run AUTOTIMER
5 press MENU
6 change first option to ENABLE
7 change poll time to 1 hr
now to add new series links
1 start AUTOTIMER plugin
2 press MENU
3 select IMPORT FROM EPG
4 now go chose the programme you want to serires link
5 save
now it will check your EPG every hour for new links
hope this helps.
