Did someone say that showing YouTube videos on your site is unprofessional? Oh come on, get real. What's unprofessional about it?
There's nothing fundamentally wrong with it, with the exception of the uncontrollable automatic and low bitrate encoding that you get - which itself might well be a deal breaker depending on the content.
The real issue is how it's perceived by your audience, with the ubiquitous YouTube Flash interface and the logo overlay. YouTube is still the land of silly kittens and amateur jackass imitators, embedded on every 15 year old's blog the web over. Your choice if you want to be associated with that. I would suggest that Vimeo or other options, with semi-pro paid options, would be a better choice for anything commercial.
