A few subjects fit under this title.
Why do I feel uncomfortable using Real's RealPlayer? At first I thought they were attempting to charge me to download the player, but it was the link from another website that directed me to Real's RealPlayer 10, which you have to submit your credit card to trial, and then cancel the subscription if you don't like it. Sounds the wrong way round to me. In fact my gripe this time, is that the player crashed Windows Explorer, three times, but it was ok with the Firefox browser!!!
And I was using RealPlayer to have a look at Ten Second Films. It set me wondering what I would do with 10 seconds. The best ones (and not the winning ones!) seem to slow down time, or speed time up by packing a lot in.
