Type: Line blending. Smooth yet sharp blend reduces vertical shimmer
Setup required: Create custom resolution via the unit
Cost and availability: High cost to benefit, scarcely sold second-hand online
Top: Corio2 tvONE 750. Below: DIDO Jr.
The DIDO LT and Jr. models by Aurora Multimedia output buttery smooth 240p, and the Jr. has the added feature of image rotation and X/Y axis mirror flipping. In essence, they function very similar to the Corio2 scalers, and have an easier setup and slightly more intuitive picture controls. However, they are sorely missing a 480i output. Given their scarcity and higher cost, get yourself a compatible Corio2 tvONE instead.
Verdict: Seldom Recommended
