Tmpge...Interlace dvd question

[monkey man]

Okay I have made a near perfect transfer of a s-vhs to dvd. I used Tmpge 2.52 plus to encod and burn to DVD-r. I used CBR 8000 and encoded as interlaced. Now after burning and playing on my TV using my stand alone DVD player I observed a minor problem. When there is high motion I get a ever so slight trailing of the moving image which makes the picture look choppy (ever so slightly). It appears the two fields at high motion are separating making two images. This by the way happens on the top half of the TV. So I re-encoded again using the top field first and it stopped my problem on the top half of the TV but now I get the ghosting on the bottom half of the TV during high motion. Other than that the picture is awesome. Now I assume I need to de-interlace. I tried de-interlacing with tmpge on the odd field setting and it stopped the problem but now the picture quality has softened up too much. Can anyone give me some advice to fix this problem. Or just give my advice on which de-interlacing setting on tmpge will stop this without sacrificing image quality.
thanks

I'm no expert, but can most standalone DVD players handle a CONSTANT bitrate as high as 8000?

99.9999% of DVD's have bitrates a fraction of that, and while I'm sure most players could handle a VBR jump to 8000, I'm not so certain there are many which could handle 8000 all the time...

I'm just speculating here, but the fact you encoded both top and bottom fields first, leads me to believe that it could simply be dragging along to keep up.

It could be sacrificing the smoothness of the fields to keep up with playing at the right speed? Maybe?...

Okay I finally fixed my problem after encoding like 30 different tests with Tmpge and CCE. The problem wasn't the encoder it was Premiere. I was resizing the original file in premiere because for some reason the overscan lines were starting to show on the TV after capturing untrimmed. I trimmed the picture and resized it to 720X480 in Premiere and exported to Tmpge. This was the problem. I turned off the resizing and BAM! problem fixed. I just now trim and resize with Tmpge only. I didn't think it would matter if I used premiere or Tmpge but it does, so never resize in Premiere or else problems will occur in your fields when you play your DVD on a standard TV.

By the way after some tweaking the DVD looks better than the original!!! I did a double blind test with some video file friends of mine and they picked the DVD or the original S-vhs ever time.

Please note by resizing I meant "cropping". I can just of the people freaking thinking that they can't trim the length of there DV in Premiere. My bad wrong terminology.

any vertical crop/resize operation performed on ntsc video will completely **** up the interlacing which results in aberrant scanlines as you observed. it's best to mask the vcr tracking with black bars(fill, crop/add borders, etc...). the dvd spec requires up to 9.8mbps sustained data transfer rate. my crouching tiger, hidden dragon megabit disc is encoded 9.8mbps cbr & my cheapo sampo player has no problems with it

That's not true. You can resize without screwing things up, but you have to separate the fields before you resize, then combine them afterwards. In VirtualDub, use the
deinterlace filter and select unfold, do the resize, the fold.

Actually, you should do the unfold and fold stuff if you do any area-based filters and if you captured both fields.
