  While watching The Planets, be prepared to fight your way past all kinds of computer animation which makes Walking with Dinosaurs seem like the last word in realism. It seems that no solar or planetary event which ever happened (or which may or may not have happened) is worthy of mention here without recourse to lovingly detailed shots of implausible-looking collisions and explosions. These come complete with sound effects, despite the fact that there is no sound in the vacuum of space, and are enhanced by a range of colours, some of which are visible only to bees. Somehow Patrick Moore's The Sky at Night manages to convey just as much excitement with little more than a couple of diagrams and the presenter's hyperactive enthusiasm. Fortunately, this two-DVD set is redeemed by both its subject matter and its sheer scope, offering all eight 50-minute episodes of the 1999 documentary series covering the history of the solar system and humanity's age-old desire to learn its secrets. Detailed indexing and scene access makes this a convenient reference source too, so amateur astronomers everywhere can finally bin those off-air VHS copies. --Roger Thomas

  This is a fascinating war story that is seldom told: the plot to kill Adolf Hitler. Many high ranking officers in the German Army were appalled by the abhorrent crimes committed against civilians and enemy troops which they believed to be morally wrong. Casualties among the German forces were enormous and many officers believed this was due to Adolf Hitler's insistence on pursuing disastrous offensive strategies. A growing number of army officers decided that the only way to save Germany was to eliminate Adolf Hitler and his supporters and stage a coup. They then hoped to negotiate a ceasefire with the Allies. The July Plot led by Colonel Claus von Stauffenberg was the closest anyone came to assassinating Adolf Hitler and overthrowing the Nazi government and Discovery Channel's Virtual History team has attempted to recreate the incredible tale in this groundbreaking documentary. With the use of state of the art Computer Generated Imagery The Secret Plot to Kill Hitler is able to recreate and bring to life the extraordinary events that took place on July 20 1944 and afford the veiwer a rare insight into this infamous plot that has previously been unavailable.
