you are certainly going for it here knob
how many are you trying!!!!
you know, i am not sure how they did this, but some guys over at ramos.net managed to create a mixed firmware from several different version of rm970 firmware, so it had much of the stale 2.10 code along with all the enhancements of later firmwares, when i load this onto my rm970 it tells me its verison 2.10, but it has all the video resume features etc of later firmwres
just a thought and i have not looked into what they did toy achieve this
www.ramos.net is the site and look for 2.10+2.23 posts
thought if we could fig out how they did it we may be able to get some bits into these no brand players
cheers
