So this was discussed a little bit in GJBD and we had a few ideas, but I thought I would try bringing the discussion here in hopes to get a more technical response in regards to the nature of standard definition display modes on PAL machines.
Currently, the only standard definition resolutions a PAL PS3 is able to diplay in (by default) is 576i/p which is unfortunately a 50hz display mode. There is no option under system settings that can allow the user to change it to 480p like on an NTSC machine. Sony have said that this is something they might consider adding in a firmware update in the future which pretty much states it's a software choice, and we know that a PAL machine is capable of displaying in 480p because you can use a homebrew app, such as an emulator, to force it into doing so. Changing tvdisplay options in xregistry.sys managed to change the display mode of the XMB, however right now there's no known method of getting the PS3 to do this for GAME related material such as PS3 games, especially NTSC games.
Unfortunately 576i/p runs in 50hz which means that for standard defenition users, games which aren't optomized for 50hz, or games from NTSC regions, will suffer from motion blurring and jerky gameplay, something which doesn't occur in 480p. This is kind of a kick in the teeth and I, as well as a few others, would like to change this on my machine. Does anyone know anything about this? Like why the PAL machines do this, how they're different to NTSC machines, where the settings are stored, or why a multi region system update on a PAL PS3 will keep the same limited display options? Any info would be much appreciated.
