And what is the source of your 480P content?

The source for all the signals, 480i composite, 480i/YC, 480p component,
and 1080i HDMI is the Philips DVDR3575H/37 HDD-DVD Player-Recorder with
digital Tuner.

Comparisons between the 4 signal types were made while watching several
HD broadcasts over the week or two.

So your assessment is based on downsampled HD broadcasts via the 480P output of the Phillips unit?

I cannot challenge your conclusions as I have never seen this unit working, nor do I have any idea how they are doing the downsampling. Is there a significant difference between the 480i and 480p?
