To my surprise, Austria's ORF aired an HD broadcast of the theatrical cut of TPM in 2012.
I didn't know such a thing would even exist. It certainly doesn't look like an upscale of an SD source to my eyes. I could have sworn they had shown the DVD version previously.

The interesting thing about this Theatrical Cut is that the quality is superior to the 1080p HDTV version, as in white areas show less heavy grain and the color balance seems more accurate (no major pink hue). I recorded it back in the 2012 onto my UPC DVR, unfortunately only from the night before the Podrace onwards and there is no way converting that stupid UPC codec to save it as a proper video on my computer without breaking the box open and causing the warranty to expire (it's only a rental).

Next time it's on I will ask someone to save it for me proper.
