BlackMagic ATEM 1 system and BoinxTV-interlaced mode

Hi,
I have a question - because I would like to buy BoinxTV and use this software with my BlackMagic ATEM 1 switcher- but I always work on HD quality 108050i and I can not change this resolution to progressive mode - please give me advice how I can connect my broadcast system to BoinxTV (I need to buy software or hardware)? Second question for BoinxTV producer are you going to change this restrict (only progressive camera system) in new version 2.
Thank you in advance
