I mentioned this in the PE thread, but it should probably go here: KeepVid has a new feature added to their KeepIt! button. You can now save files in mp4 format, rather than just flv. This appears to be a beta feature, so it may not work with every file, but it's worked for me so far. This may save a lot of asking for conversions and download links, since all you need to do is add their little button to your browser's toolbar. Then just hit the KeepIt! button whenever you see a YouTube video you want to download. It'll give you two download links, one .flv (lo) and one .mp4 (high). Click for the mp4 version and save the file.
