if i can make a suggestion, go to youtube and check out good eats a chuck for chuck or celebrity roast. If youre not familiar with good eats the chef is Alton Brown from Georgia, he is a well known chef on food tv and tends to explain things about cooking on a level the regular joe can understand. he explains why and what makes things good. He is a little cheesy so bare with it but his chuck for chuck and celebrity roast episodes are very good info for pot roast. If you are interested you can see all his episodes on http://www.surfthechannel.com/ look for the channels section at the top of the page, go to the tv section then go to the G section and look for good eats. also they have all kinds of online tv and movies free.
