2) I use a Compro TV Card. This card has a feature called Recording Scheduler. You can schedule a time for Compro to record a TV program. Compro will boot the PC, start the Compro Software and Record the program. However, what will happen when I install Media Portal? Will I be able to do this?
The feature is probably not in the TV Card but in the Compro Software. Anyway - MediaPortal has that feature too so that's no problem! You will find PowerScheduler in the plugin section in the configuration program. I think you have to use autologin for it to work (but I can be wrong).
This is also the procedure I recommend for autologin:
Start-run type "control userpassword2" hit enter.
Select your username and uncheck
"Users must enter a user name and password to use this computer"
