Hello Bryony,
Please accept our apologies for the late response.
I will try to give you some tips to avoid the problem. The reason of quality degrade is that your images have high resolution, such as 2736 x 3648, and you save it to DVD which is only 720x480. When you save to HD 1280x720 avi is much better. Aspect ratio choosed for the project is also important. You will get best results if you select 4:3 aspect ratio for your project. You should also save to DVD Pal profiles, not DVD NTSC.
Not sure what can cause the problem with text... But, I would recommend you to try the latest version
AVS Video Editor 6.0 which we have just released.
I hope it helps.
Best regards.
