How are you judging the quality? On your computer?
Remember that DVD video is only 720x480 -- the non-square pixel equivalent of 640x480. That's fine for a TV, but your computer screen is probably 4x or more than that resolution. So, if you watch it full-screen on your computer, it's going to look terribly pixelated! So test drive it on your TV.
Also, you don't say what you're using as source video. But if it's coming from a hi-def source (say an AVCHD file), it too is several times the resolution of your final DVD file. Since you're going from 1920x1080 pixels to 640x480, there will be a lot of pixels tossed away in the transcoding.
As for your photos, if you take our advice and rez those photos down to no larger than 1000x750, there shouldn't be a lot of difference between the original and the DVD. But no matter how high the resolution of your original photos, you're still only getting the equivalent of 640x480 in the end. That's the nature of DVD video.
I guess I didn't make myself clear enough. The video and photos look great on my computer, but look pixilated when burned to a dvd and played on a TV. Thanks.
What are the sources of your video clips ? What dimensions are your still images ?
Insanity is hereditary, you get it from your children
Pixelation IS resolution, mirsy.
If it's something other than that, can you post a link to a clip of the video posted online so we can see what you're talking about.
