    I have tv shows on my computer in avi format that I wanted to burn to DVD so I could watch them on my TV. So I came here like always and found the perfect guide, The AVI2DVD guide, which I followed and it was awsome. When I converted them it took up 9 Gbs on my computer and thats for the image file and the dvd files but I forgot I dont want the image so I just deleted it anyway. I thought that was a lot for a 45 minute, 350 MB video. I encoded the second episode which took up another 9 Gbs thinking that I might do two episodes per dvd but after they were done and I went to go burn them with Nero its around 5 Gb and wont fit onto a normal DVD-5 4.7Gb. This cant be right, I dont want to only do 1 episode per dvd thats riduculous. How does a 350 MB, 45 minute movie turn into around 2500 Mb? This should seem fixable and any input is greatly appreciated. Thank You

    Oh yeah I was also wondering how I can make a cool looking DVD menu so that I could select either Episode 1,2,3 etc.. Thanks

    Well I don"t use AVI2DVD but in general you should have no problem fitting 2 to 2.5 Hours of Video on a Single 4.38gb DVD-R as Long as your Source Files are of High enough Quality.....

    What Determines how big the DVD files will be is the Length of the Video and the Bitrate used to encode the Files to Mpeg-2/DVD format...
    For 45 minutes of Video to Fill up a Full DVD the Encodeing Bitrate would have to be about 13,150kbs which is about 4000kbs Higher than is allowed by the DVD standard so in Theory the Disk shouldn"t even Play in your DVD Player at that Bitrate.....
    I don"t know what is going on But it seems like something is really screwed up somewere....

    You should be able to Fit at least 3 45 minute Episodes on a single DVD without any problem at all, if you wanted to use a Different DVD Standard and sacrifice some quality you could fit from 4 to 6 hours on a DVD if you wanted....

    If you are trying to put 2 or 3 Episodes on a DVD you should be loading all 3 Files into your Program at the same time because you can Only Burn one ISO or Video_TS folder to DVD....

    Maybe you might consider just useing a different Method?? What I do is I use a Good Standalone Mpeg-2 encoder Like "Tmpgenc" or "MainConcept encoder" or CCE SP" to encode each of my Files to DVD Compliant Mpeg-2 format but useing the Correct Bitrate so that all of the Files will fit on a DVD without being too big, (i use a Bitrate Calculator to find out what to set the Bitrate to based on the Length of the Files, to fit Three 45 minute movies files on a DVD you would need to set the Video Bitrate to 4125kbs and the audio to 384kbs)

    After I have encoded the Files to Mpeg-2 format I put them on to DVD with a Manu were I can select which movie I want to watch useing a DVD authoring Program Like "Tmpgenc DVD author" or "MediaChance DVDLab(Pro)" which also lets me add Chapters and other Features to my movies, when you are done it will format it all into a Video_TS folder which it then Burns to DVD For you or you can Burn it yourself useing nero .....

    There should be guides in the Guides section on how to do it this way or a simular method and most of the Software is available for free for 30 days.....

    Good Luck

    Thank you so much, that is exactly what I needed and after some research after posting the thread I relized that my bitrate must have been way to high. The only thing is that when doing AVI2DVD it automattically sets the bitrate to 8000 or something and I'm not sure if you can change it while it is going because I've been alseep during it. I have recently just gotten CCE and DVD Lab so I think I will be doing some experimenting with it. But thank you so much and I will try to figure out how to turn my bitrate down. And one last question, with a bitrate with around 4000 or whatever you use, am I going to lose quality?

    After a certain amount of Bitrate you do not really gain any More quality, generally between 4000kbs and 6000kbs is ideal for most video but the encoder also has a Lot to do with it as some encoders can produce better quality at a Lower Bitrate than other encoders can at a Much Higher Bitrate, that is why not all encoders are equal....

    CCE SP 2.70 is the encoder I use but it is very Difficult to use properly so you generally have to use a frameserver like AVISynth or Virtual-Dub with it to get the best results Pluss you really have to know what you are doing when it comes to Mpeg-2 encodeing to get the best results as many of the settings are Confuseing and if these settings aren"t set correctly based on the Type of video you are encodeing you will not get the best results.... I only suggest useing CCE if you really know what you are doing or Try a Different encoder Like Possibly the "MainConcept Encoder" which is Much easier to use and set up and Is just about as fast and produces very good Quality.....

    Cheers

    Alright, thank you again, maybe I will just try Mainconcept encoder because I dont really know what I'm doing that well. Well thanks again for your help, its not very often I get questions answered so thoroughly and simply :)
