Nokia E70 video playback resolution

I have been trying to find information on what Nokia 5300 and Nokia E70 is capable of playing back in terms of resolution. I would love a E70 if it can playback full-res video, and my girlfriend wants a 5300. This thread seems to imply the 5300 is unable to play back full-res video, and I suspect the E70 has the same problem, given its huge resolution.
