AVCHD to DVD quality help

[daz1976]

Hello

This is my first time here so be gentle!

I'm not totally a video editing virgin but I am having a few issues that I hope somebody might be clever enough and helpfull enough to shed some light on for me.
I recently got a Canon HG10 and using VS 11.5+ converted my holiday video to DVD for family. The thing I'm finding is that the resulting DVD seems to be covered with a mesh type pattern that is very apparent on movement over areas such as sky etc. When I do the same conversion with Nero Vision it is clear. I've tried upper and lower field and upped the VBR to 9000 with 2 pass but none of it is helping this issue. I can's see what Nero's seetings are as it is far more automated to check what it is or is not doing that VS is. Any ideas would be very welcome as I like using VS.
Thanks in advance.
