Like I said, the DVD Video specification requires that video be encoded to MPEG-2, that said, there are plenty of DVD players that can play other types of video like Divx for example.
There are so many ways to encode to MPEG-2 and author to DVD on the PC it’s bit of a mine field. On the Mac it’s far, far simpler.
This my be a good start for you:

You are not exactly loosing the frames, rather interpolating them from 29.97 to 25.

I rate the Nattress plug-in for doing SD standards conversion, not HD to SD. In this instance I suggest that you contact Mr Nattress himself for help and advice, you paid for his product and part of that should include a certain level of support.
A professional Standards converter would very likely have the words ‘Snell & Wilcox’ on the front:

Just to be pedantic, there is no such thing as ‘NTSC HD’, in the same way as there’s not such thing as PAL HD, HD is referred to by vertical frame size along with frame rate and whether it’s interlaced or progressive, so ‘NTSC DVCPro 720’ should actually be ‘720p 30’ (or 29.97).
So you are attempting to go from ‘720p 30’ to ‘576i 25’
The reason your subtitles are drifting is because you are removing roughly 5 frames per second.
To be perfectly honest, I rate the Nattress plug-in very highly, but the only way you’ll get this done properly, without shoddy results, is to use the services of a professional, broadcast quality, standards converter.

Encode to 640×480 square pixels. (you may wish to deinterlace)
Set the HDTV to 4:3 (monitor will place black bars left and right (pillar box) and scale movie correctly.
Stream movies to HDTV
Job done.

The DVD video standard requires that video is encoded using MPEG-2, that is, if you want it to play back on a DVD player. If you just want to put on a DVD data disc so computer can play it back you can use ‘anything’ you like.

Is that the peak bitrate? I thought I had read somewhere there is a peak bitrate one is able to reach on codecs
No, the peak bitrate setting is simply saying to the encoder that you do not want the bitrate to go past the set value.
Different codecs have different theoretical peak limits but it’s more that they can’t make use of the extra bits than you can’t input the value.
For example Prores422 can deal with many hundreds of MB/s but a 3GP codec can only deal with a 1Mb/s before there’s no point in giving it more.
Commercial DVDs can range from anything between 3 and 8.5Mb/s.

The file I’m working with is was shot on a RED
Lucky you! – Lovely stuff to work with.
The final edit was exported from FCP at ProRes422 HQ (720×486)
Just to be sure, is this 4:3, anamorphic 16:9 or letterboxed 16:9?
I brought that file into Compressor and tried several settings. My final settings were:
-Export Using: WMV 9 Advanced
-2 pass CBR
-Quality 100
-20,000kbps
-Size and Rate: Current (I kept it at 720×486 and 29.97)20,000Kb per sec!!! Are you sure, 20 Megabits per second!? – Why or how did you decide to go that high?
I’m currently delivering a similar frame size for a client at 1Mb/s, so you simply don’t need to go to anything like that amount, you are wasting bits as there is a limit to how much information each pixel needs.
I’d suggest you don’t need anymore than 3Mb/s even for difficult content.

I have a client asking for some high res WMVs. What settings would you suggest?
In other words, “how long should my piece of string be?”
What do you consider high res? What is your source? Who is the clients audience? How high or low are the clients expectations?
There is no ‘peak’ bitrate as such. you could go to 15Mb/s or higher if you wanted to.
Your peak bitrate is determined by the available bandwidth or a mental calculation that involves a combination of your frame size, how complex your footage is and what you consider to be ‘good enough’ quality. There is no magic figure only very rough guides.
WMV is capable of just as good quality as the equivalent Quicktime CODEC using similar settings.
Tell us how you are doing it now and well tell you if there’s anyway of improving your workflow. Be as detailed and specific as you can
