Will a Blu-Ray disc play on a standard DVD player? The reason I ask is that at some point, when Blu-Ray players become more stable/reasonably priced, I will take the plunge and get one. In the meantime, I am quite keen to get the new Dave Gilmour DVD and this is available in Blu-Ray and standard DVD. I would rather get the Blu-Ray for future use, but, no point if it wont play on existing equipment! Told you it was a dumb question!!!!!!
