No.
You will just confuse your clients, lose market brand and risk losing your business altogether as people WILL get confused and wont understand why it has changed.
Perhaps just add a tagline to your company name: so you keep your name and underneath it in all your letterheads etc run a line explaining your wider services ‘first for DVD authoring and creative services….’.blah, blah, blah
You can keep your name but give it a fresh look with a different font, brighter colors or some logo or another.
