Vegas Pro downconverting troubles

Hello Everyone,
I thank you in advance for all the help you be able to offer me, I am having a lot of trouble. I will list all my computer specs and everything at the end of this post. Here is my issue, Whenever I shoot my video and down convert to make a SD dvd the video is never smooth. there will be hickups sort of speaking. the audio and video will skip or stutter every so often. my Last job was a nightmare as I could burn a Bluray just fine but when making the file for dvd it was a mess. I had to render a Bluray then run that through DVD decrypter with a Bluray to dvd copy function and import the dvd back to my PC to now edit for my DVD file. I ran some test footage recently in different format to down convert and same result, stutter footage. so I am at a loss of what to do next, any help or insight would be great.
here is my workflow with specs
shooting video with sony hxr-nx3 (tried 60p and 60I, both with same results) I also tried the simultaneous hd/mp4 recording but it did not produce a mp4 video on sd card
import to pc using Sony Content Management utility
PC is intel I7 2600k (no OC) running windows 7 (up to date) gtx 670 gpu ( gpu rendering has been disabled in Vegas as it caused video files to be unwatchable) 8GB Ram
open in Vegas pro 12 (all updates done)
make my edits
render as mpeg-2 DVDA ntsa widescreen video stream
render ac3 audio

now before even burning with dvda, if I watch the mpg file is will have the issues. my original source files from camera do not stutter, so I'm losing it through the rendering process on Vegas.

I hope someone else has maybe had same issue and can shed some light for me, thanks so much

Upload a 10-15 sec clip that exhibits the issue, so people see what is happening. I would trying converting a 1 min chunk of 60p video to something like DV 29.97p or XDCAM 29.97p, then convert that MPEG-2. You do not really list your project settings or rendering settings for each stage.

my project settings always match my source files, and rendering setting were left at stock Vegas setting for the DVDA widescreen video stream. I did experiment with same video clip that was having trouble and did find out that if I do render it to a NTSC DV .MXF file first then re-render that to the DVDA mpg file to send to DVDA it does come out smooth. I feel like there is always extra steps I need to do to complete one project, but I'll take this fix as its less work then what I had to do before....

at the 5 second mark.


edit: well in an interesting twist, the video uploaded to youtube doesn't display the issue, but played back on my pc or if I try to make a dvd with it the dvd will show the same freeze. now I have no explanation what so ever.

Workflow are often not 1 to 2. I would try this workflow:

Vegas:
Convert camera footage to xavc or xdcam.
Edit
render to xcdam 30p.

Rendered file can be uploaded directly to YouTube.

In DVDA:
build DVD using the rendered xdcam file
Build DVD widescreen
burn dvd
