- 25gb thought they said 250gb was possible using either 250gb or 25gbg disc anyone know of developments for that.[/QUOTE]
25 GB = a single layer BD-R format, the most common and cheapest
50 GB = a dual layer BD-R format, usually about 3-5x times more expensive the SL media
100 & 120 GB = a triple-layer and 4-layer “BD-R XL” format, extremely expensive (> $60 a piece) and incompatible with existing blu-ray readers and writers
A BD-R media with larger capacities than 120 GB do not exist yet.

[QUOTE=robbi;2563167] 4. What is the best $Â£1 or sub $Â£1 single layer price discs at the moment.[/QUOTE]
Pay a little more and get a decent media like Verbatim (not LTH!), Panasonic or Sony.
