Another common mistake is changing the settings if your source is MPEG or any other format with an adjustable bitrates. This only applies if you're editing for archiving, check your editors settings. It's usually called "smart render" or something like that. When you use that the only thing that gets re-enecoded is where the edits are. You save a lot of time because it's really just a copy from the source and since there is no conversion there is no loss in quality. This doesn't apply to something like DV becsue there is no settings.
Don't ever scale video up either, let the player or hardware handle it.
Don't ever deinterlace either especially for archive material, again let the player or hardware handle it during playback.
