Anyway, every video format is converted to MPEG2 when generating a DVD, the less format conversions are made, the better...

Under certain outputs in my Video software such as say Blue Ray, I can choose between MPEG-2 or H.264 formats. If I choose a Video CD the format is MPEG-1 and an AVDHD output goes to H.264 . So that is not always the case but it is true a standard DVD does usually go in as MPEG-2.
Format changes are possible without loss of clarity, but I agree you are best to start off in the output format and any compression of course reduces clarity somewhat so avoid compression till needed.
