hey... trying to find an open source app to create a dvd file, as well as play the file... can anyone give me insights/pointers to software that you've actually used/got exerience using/knowledge of... basically, i'd like to be able to create test dvd files.. and to play them. i'd also like to experiment with incorporating information within the dvd information in a manner that can't be seen by the human eye, and then be able to extract the information with a separate app.. trying to search through google isn't causing any real hits! thanks bruce bedouglas@xxxxxxxxxxxxx
