VK, excellent post - thanks for taking the time to share your experiences.

Couldn't agree more about taking 1080i down to 720p and still looking great - you are seeing the real detail and cleanliness of the transfer rather than upscaled SD mpeg artefacts. I am confidently guessing this could be taken even further and that a 1080i HD-DVD downscaled to 480i would still look better than the SD version for the same reasons.

Having said that, the Toshiba's downscaling, as you have found, is known to be poor so you'd want a better device to take it's 1080i signal and downscale for this to work well.

Cheers,

Mark
