If you're recording PAL, you either need exactly full-height (576), or
half-height (288), 480 will just utterly ruin the video.  You can use
scale (after deinterlacing) if you wish.

I also recomend a much smaller keyint than the default, and using
vqscale instead of vbitrate.

Loses?  How does it lose them?  "loses" could mean anything.

Try encoding with -noskip and -mc 0 if you're really sure you don't
want any skipped frames.
