Encoding PAL to Progressive MPEG2 question

I'm constantly reading reviews of DVDs stating that the video is interlaced, so I decided that from now on all our DVDs would be progressively encoded. But trying to find out how to do this isn't easy. Questions over at Apple' own Compressor forum haven't given me a proper answer, and there's no clear-cut instructions in Apple's Compressor manual either.

We issue movies on DVD that were original shot in film, and have been telecined to PAL (usually to DigiBeta) at 25fps. I then capture these in to FCP and export to Compressor and the DVDSP.

Here's what once user at the Apple forum suggested:

1. Export from FCP using Compressor
2. Apply the DVD preset you want
3. In the Inspector window, click the Frame Controls tab
4. Set the Resize Filter to Better or Best
5. Set Output fields to Progressive
6. Set Deinterlace to Better or Best
7. Uncheck Adaptive Details
8. Hit Submit and give your job a name
9. Import .m2v and .ac3 to DVD Studio Pro
10. Author and burn DVD

However, opening the encoded mpeg2 video stream in Mpeg Streamclip tells me this:

Video Tracks:
224 MPEG-2, 720 ? 576, 16:9, 25 fps, 7.50 Mbps, lower field first

It's telling me that the video is "lower field first", so surely this indicates that the video is still interlaced? This is why I am so confused.

Can anybody please help?

I'd like to add that I also checked the encoded MPEG2 file with an app called "VideoSpec" and this too indicates that the file is "Interlaced, Bottom Field First".

Does Compressor work properly I wonder?
