The DVD works well, so no issues there, but ouch this production is god awful. Sense and Sensibility is my fave Jane Austen book but this adaptation is strident, stilted and unbearable to watch. Sometimes the BBC goes too far with wooden, shrill characterizations of Vidtorian/Regency England society to the nth degree.
Instead, I highly recommend the adaption with a stellar cast including Emma Thompson, Kate Winslet, Hugh Grant, and the wonderful now unfortunately deceased Alan Wickman, Tom Wilkinson, and Gemma Jones. It is my personal favorite adaptation. It is charming, brings the characters and time period vividly to life, and is infused with the wry humor that is a central feature of Jane Austen's literary style.
I also recommend its precursor, the 2008 BBC TV MIniseries adaptation you can buy on DVD also with a wonderful cast including Hattie Morahan, who, in my mind, is the absolute personification of Elinor Dasheood. When I think of Elinor, I think of her. It also stars Janet McTeer and David Morrissey as Colonel Brandon.
