My ossc works quite well with my tv, 240p and snes without issue, my PAL PS2 can only do line 2x bob or pass-trough. When played in 60hz mode I can also output 480i line 4x bob.
Recently I got myself an old PAL xbox and hooked it up with a rgb scart cable to my ossc. When outputting 50hz I am limited to pass-trough and line 2x bob, as expected. However when running 60hz and turning on line 4x bob, I get a blurred picture. No blur when using other modes. Something else to note is that my TV gives me no input information on my source when running 4x 480i PS2 or XBOX.
Anyone else experience a blurry image when playing an xbox on line 4x bob? any tips? (allowing upsample2x does not help)
