rss Not feeding thumbnaisl of movies

[superstan]

Hi

Im using Rss to feed onto my website - the hyperlinks work OK - But the thumbnail of the movies ends with .mpg not .jpg Tius the image is a red cross
Can i alter it so it renames the thumb as the correct Thumb_url.jpg not Thumb_irl.mov or mpg

help please
