You may be able to do it if you get a fast class 10 sd, but i personally don't think the framework can really handle it.and it would just be easier to get a digtal video camera.
But just like ths cool Rom we gotta try.
what error do you get from playstore after you first log into gmail.
i guess you tried this.
Go in Settings / applications / Manage applications , choose 'all ' tab
Then clear all data and cache of both Google play store and google services Framework
Reboot into recovery and wipe cache and wipe Dalvik - Cache
Reboot wait 15 minits and relog into gmail then wait till sync clears in status
line then try play store after 5 more minits
