When you render to DV, your titles becomes compressed to DV. So ideally you render to a higher quality format. What do you mean by "does not look great"? Are you talking about DV50 or Uncompressed? Also, are you working with interlaced material or progressive?

Pjpeg is not advisable for interlaced footage due to the compression scheme. M-Jpeg is fairly similar to P-jpeg, but is designed for interlaced formats. P-Jpeg doesn't have a set frame size, so you can change the frame size. What do you mean by "the frame size changed"?
