I am using DVD Architect pro V6.0. The Problem i have is i want to make a bluray of a TV season for my own use. When i look at the AVI files they total 3.4gb. When i add them into DVDA in bluray mode they come out at near 80gb!..am i doing something wrong here? I want to fit them onto a 25gb disc
A whole TV season for 3.4GB doesn't sound right. That seems too small. Either the way you're looking at the sizes is wrong or the video files may be corrupted and show the wrong size or something.
If you're sure about the file size make sure to not have DVDA recompress your files for you - I'd suggest using one of the templates on Vegas but you will have to keep audio and video separate, as per the templates.
Also, check to make sure your project bitrate is not too high (will be used for recompressing and menus) and that it's set to AVC and not MPEG-2.
AVI is definitely not the right format for saving BluRay-ready files. AVIs, in factor, are virtually never used in the industry or for private use anymore.
If you are saving high-def video as BluRay-ready AVCHD video, you can fit about two hours of video on a single BluRay disc. You might be able to squeeze a little more on using compression, but two hours on a disc is a good rule of thumb for home-burned BluRays.
A broadcast TV season is more like 20-30 episodes. Netflix shows are more like 8-10 episodes. You don't say if you're swiping a half hour show or a one-hour show but, either way, I sure wouldn't recommend try to squeeze an entire season on a single disc!
