1080p50 (as 50i) on bluray is softer than 1080p25 (50i psf)

Hi,

It seems my workflow is not optimal yet for burning 1080p50 on bluray.

When I record 1080p50 and watch it on my LCD TV (Panasonic GW10) from the camera it looks as good (and of course smoother) as 1080p25, no matter if I set the camera output to 1080p or 1080i.
When I burn 1080p25 on bluray as 1080i (progressive segmented frames) it looks as good as directly from the camera.
But when I burn 1080p50 on bluray as 1080i (Top field first) it looks quite a bit softer. That seems logical because it´s real interlaced. Every field is different and needs to be deinterlaced. But why is that not a problem when outputting directly from camera to my TV as 1080i?

My workflow is Premiere CS5.5 and then frameserving directly to Tmpgenc 5 (x264)

I really like to get the best resolution out on bluray. Am I doing anything wrong?
 
I'm not exactly sure why you'd wanna burn 1080p50, the file size is twice as big as 1080p25 and its obviously giving you some issues when 1080p25 isn't, so why not just stick with 1080p25? the motion probably looks way better at 25 vs 50 anyway.
 
I want to burn 1080i50 out of 1080p50. 1080p50 is not officially supported on bluray. The motion looks smoother @ 50 p/i
 
Nope. All DVDs and Blu-rays coming from film are progressive – the player adds pulldown if needed.

@ FelixGER: It depends which hardware is doing the de-interlacing.

If you have Premiere, you'll have AE too, do you?

After Effects can do much better re-interlace than Premiere, just feed the 50p to a 25 fps timeline and export as 50i (interlace actived).
