I've been an avid reader of these forums for quite some time now, but I finally have found an issue in which I was unable to find a definitive answer to my question.

Here is my situation:

I recently purchased a 61'' Panasonic DLP (PT-61DLX75). According to Panasonic, this TV will properly perform 3:2 pulldown and properly deinterlace a 1080i image and display it with little to no content loss.

I had my doubts so I ran the test pattern SMPTE 133, as described in a hometheatremag article that I can't link to because this is my first post. The test pattern is also available on DVE. Sure enough my TV fails this test, meaning it is using the bobbing method to deinterlace my 1080i feeds.

This leads me to my two questions:

1. Does this mean that the bobbing 540 line display that is being shown now on 1080i feeds is actually displaying less detail than a 720p feed? Would I benefit from setting my HD DVD/Blu Ray player to 720p because of this?

2. Would a video processor/scaler(set at a 1080i output) that properly executes 3:2 pulldown eliminate this loss of detail or will the junky deinterlacing method in my television just redo the deinterlacing and screw it up again?

I'm new to signal processing so any help would be greatly appreciated, thanks.
