These mp4 files are 720x576 and I think this is the resolution of a standard pal dvd, isn't it?

PAL, yes.. but NTSC DVD is 720 x 480... not 576. You are already higher-res than an NTSC DVD, but it's a non-standard hieight (though 576 is supported by the h.264 codec). Encode to h.264 (which it may already be, inside the MP4 "wrapper"), profile 3.

You may wish to crop it or something.. 720x576, a 1.25:1 aspect ratio, is a bit square in this day of 16:9 ratios. normal DVD is 720x480, which is 1.5:1 (3:2).

the old NTSC TV ratio of 1.33:1 (320 x 240 - 4:3) was fairly square, so your 1.25:1 is going to look really square and won't "fill" any standard display with aspect ratio preserved, other than maybe the one on your camera or something.
