best way to resize sd->hd

Try shooting interlaced squeeze mode and see what happens. Because the "squeezed" image has to be "stretched" back out to get the 16:9 frame, it takes the interlaced edges and enhances them (read: makes them worse). It's just a bad thing to do.
Well, you're shooting in "SD" format no matter what. The DVX is not an HD camera.
The CCDs in the camera are native 4:3. To get a 16:9 frame, it has to crop from the top and bottom of the image. 4:3 is not cropped. Letterbox is still a 4:3 image but has black bars on top and bottom. Squeeze actually crops the top and bottom of the frame, but compresses the image horizontally to record it in a 4:3 frame and the image is stretched out to anamorphic 16:9 upon import to your NLE. Squeeze is the best way to get 16:9 from this camera, especially if you intend to up-scale it to an HD frame size. Read THIS POST for a great explanation about why this is so.

I shoot letterbox ,my dvx have no squeeze , then strech the image with vegas , quality its OK
The other guys know more about this than I do, however I have shot several projects with the dvx100b and upressed it to 720p using magic bullet frames to deinterlace, and instant hd to upres.
I shot most of them in 480i squeeze because they were multicamera shoots also using ag dvc60s which cannot shoot progressive. On single camera shoots I prefer 24p or 30p since the upressing seems to work a little better not having to deal with interlaced footage.
All that aside, I have usually managed good results at 720p.

Why would you need to deinterlace 24p footage?
Shoot Squeeze and set your Vert. Det. Freq to THIN. This will give you the best possible base resolution for uprezzing to HD.
I meant the deinterlacing step was because I frequently am up resing 480i footage. Of course you don't deinterlace progressive footage
Shooting 24p or 30p would be my recommendation. Then all you have to do is upres
I am a little confused here. Did you mean to change the size of images with the help of image resizer? If not, does it help? I am almost a green hand here. Any suggestion will be appreciated. Thanks in advance.

If you have after effects, the high-quality upscale filter is pretty good.
You can also export to an image sequence and use Photoshop - make an automated action that upscales all the images in the folder, then import those as an image sequence to an HD timeline and re-render.

Photoshop is a great way to upres SD footage. There are several great plugins made to uprez still images to huge sizes. I recently uprezzed a DVX100-shot feature to HD by exporting the whole thing as an image sequence then batching it through Alien Skin Blow-up in Photoshop. It converts edges in the image to vector art, then uprezzed based on the vector map. You can dial in custom sharpening, edge contrast, and grain. Looks better than any other method I tested, including After Effects. But, it did take almost a week of processor-intensive computer time.
