You will need to create a custom easy Setup.
Select the PAL DV anamorphic. Open up Audio/Video settings > summary tab. Change the sequence settings to ProRes 422 PAL 48khz anamorphic.
As you are not capturing footage, change the capture preset to Generic and the device control to Uncontrolled device. that will stop it nagging for a firewire device like a DV camera or deck.
Unless you have a video playback card (Decklink, Kona etc) select none for video playback.
Save this as a custom easy setup with a really usefull name and description like ProRes 422 PAL 48khz anamorphic 720 x 576. Voila
