720x486 - OK for DVD?

I'm editing 10-bit uncompressed NTSC for the first time and have just learned that it is 720x486 instead of DVs 720x480.

One of my output formats will be DVD. Is there anything I need to worry about now (beginning of edit) to make it so that I can export an mpeg file for DVD? Any compatibility issues?

Also, is there a specific reason for this slight difference in resolution?

Thanks,

From the Compressor User Manual (search for 486).

If you want to transcode a normal size standard definition (SD) source media file (720 x 486) using an MPEG-2 NTSC setting, your output media file will be automatically cropped (two pixels from the top and four from the bottom) to achieve the MPEG-2 required dimensions of 720 x 480, unless you already specified cropping attributes. This crop attribute is only temporary and is not saved in the setting. You can see the automatic crop in the usual way, by double-clicking the setting in the Batch table to open the Preview window.
