Smart Recording on Plex Server?

[Peter_H]

I'm using Plex Server on a NAS.  I've so far signed up to just the Plex subscription, but am wondering what extra (if any) would I get from the full IceTV subscription vs Plex subscription?
There is a place on the IceTV website that says you don't get smart recording on the Plex.
Does that mean I can't record from the IceTV app, record series that haven't started yet, etc?
Thanks in advance,
Peter
EDIT: IceTV support has advised me that for Plex users, there is no advantage to having anything but the Plex subscription
