timeshifting all programs (1 Viewer)

[sand]

is there an option to timeshift all channels so when rew you can watch two or more timeshifted programs...

also, i think in dvbviewer) if you missed start of movie and then start to record it after 10-15 min when you press record it would record movie from the start ....

are there any options like this in mediaportal

thanks,
