That's just the thing, JCPentax in one of the other threads stated that it was removed as a feature because its implementation actually caused problems with the video. Keep in mind, contrast-detect autofocus takes a lot of processing power, and running that side-by-side with the actual video recording when using such a low-compression format may be the problem here. Sure, the t1i might be able to use CDAF in video, but last I knew it also uses a format for video with a lot more compression.
Besides that, really, the main reason to use a DSLR for video is shallow dof. Shallow dof is not a good thing to mix with autofocus in video. If you want a video device to focus for you, a camcorder is a far better choice.
