Convertin video in more sessions (resume encoding)

Is there a way/programs that support converting/encoding video in sessions, for ex, now make 10%, tomorrow make 30%, etc… (from 1 input file to 1 output file)…

i tried windows media encoder 9, it doesn’t support PAUSE.
i tried EO-Video (which seems nice, join many files into 1, etc)…

but till now i didn’t find a program to allow resuming.

any ideas?

Thanks in advance…
