Maybe its just me however my Samsung C650 no longer has the resume message when playing a video.
Normally i would see the message when a video starts saying press blue to resume last position.

I've run some tests and it does however show on videos that i had watched using the last version, if that makes sense.

So if i watch a video using 2.6.4 that i had started to watch under 2.6.3 then i DO get the resume message.
However if i start watching a new video under 2.6.4 and came back to it, then no resume message.

cheers
