As has been mentioned before, with film material at 25fps, it's the same thing.
I don't get it. So just because it's 25fps, it's automatically 1080p?
No, not quite, but because it's 25fps, there are no issues with 3:2 pulldown. At worst, you have to worry about 2:2 pulldown, but since both fields come from the same frame, it looks progressive (i.e. no combing). There are no video frames constructed with two fields from separate film frames, as there are in ATSC/NTSC.
Also, with h.264 there's a PAFF encoding scheme which effectively allows you to actually encode 25fps at 1080p. From what I've read, SkyHD and Premiere both use this kind of encoding. Don't know all the details, but that's the gist.
