I'm not a big fan of buying DVDs, I only have about ten movie DVDs & I have a big collection of Doctor Who DVDs, if I wanted to start a big collection of DVDs should I stay w/the regular ones' (how long will they be around?), or start with blue ray DVDs (are regular ones going the way of VHS, beta). And my Doctor Who collection which is British, like alot of British shows seem to stick w/regular dvds, so what should I do, stick w/regular or start a blue ray collection?
