movie files

[cmcconathy]

for about a month now every movie i download says it is 100% downloaded. when i open the file with my burning software: convert x to dvd, and xilisoft dvd creator - the file always says "duration 1 minute". i never had this problem previously. the files i download are above 699mb. i dont know if this is a downloading problem or what. someone please help. it takes as long as a normal movie file to download yet its saying its only 1 minute long. thanks chris
