Hi guys, first post on here

I'm pretty new to media portal but have started using it because of its good support of dvb-s/s2 and HD channels.
I've set up mediaportal working with my Nova-HD-S2 card to watch the freesat/sky channels. This works fine and allows me to record programs which are currently showing or record manually when there are no listings.
However my problem lies when I try to schedule a recording of a program in the guide listings which has not yet started. When I tell mediaportal to record a program in the future, regardless of wethere I am using the tuner or not it will always crash to the desktop without adding the program to the schedule and windows will come up with a message saying "Mediaportal has stopped working, do you want to close this program". Your only option is then to close the program and restart it and again when it restarts it works fine until you try and schedule a future recording.
I have no idea what the problem is, I have tried various different xml guides and restated the computer and rescanned the channels several times but to no avail. Is it that mediaportal simply doesn't have the campability to schedule recordings? or am I doing something wrong?
Thanks for the help (Rig specs below)
