Peter, I can confirm that myself sir, the Oppo does native output for these resolutions:

480i
480p
576i
576p
720p/60
720p/50
1080i/60
1080i/50
1080p/24

this is via HDMI or HD-SDI mod for any region DVD or Blu-Ray disc, component doesn't support 1080p/24 as far as I know, also 1080i/50 can be output as 1080p/50 etc. etc., the Oppo features source direct which when enabled is just that, source direct untouched output for all NTSC and PAL resolutions

the Oppo can also be set for NTSC output only and will convert all PAL, likewise can be set for PAL output only and convert all NTSC, finally the multisystem/native output we are talking about is direct unconverted

thanks Peter, any other questions just let me know at anytime and I will be happy to answer them
