it has to do with the settings ur burning at... u have to adjust the sound and image quality.. cuz basically the program is going to try to convert the video to some high definition crap...

i use ulead dvd factory.. and it has all the adjustments for that stuff. u just kinda have to search for them

I did a quick search on Sonic's site, I think this is what your problem is.

The "official" DVD disc sizes are confusing because they do not follow the conventions used for other digital media. In the DVD world, 1 Gigabyte is 1,000,000,000 (109) bytes, whereas in the computer world, 1 Gigabyte is 1,073,741,824 (230) bytes. Therefore a 4.7-GB DVD contains less data than a 4.7-GB hard disk. Usually the quick increase in video size has to do with one of three things:

1) You have edited or trimmed video in MyDVD, and MyDVD is re-encoding it using it's default 8mbps encode/transcode rate. Any video that is captured or brought into MyDVD at a lower bit rate will be re-encoded at 8 mbps. However, if the video is captured at "Good" or Better" within MyDVD and not edited, the lower bit rate will be held. This trasncoding issue will be addressed in a future release.

If you wish to edit a project and maintain a lower bit rate, then it's best to either capture to hard disk a DV.avi in MyDVD and edit the piece in a third party application (Windows Movie Maker 2 is available for XP users). Then use a thrid party transcoding application to encode the DV.avi to the bit rate that works best for your length of video.

2) Your video resolution was too small and MyDVD/DVDit! is calculating the size it will be after it is transcoded by the program. Having video that has a lower resolution than 720x480 will be bumped up to this DVD standard resolution which will increase the size. If you are using MyDVD and .avi files, this video will be autmnatically transcoded at 8 mbps constant bit rate. For more information regarding appropriate files and specifications, please refer to the "Preparing Files" link below.

3) The software is calculating the size that your audio will be after it has converted it from MPEG-1 layer 2 (or MP3 using MyDVD) to DVD legal .wav files. For an explanation of this, please refer to the "How Much Can I fit on a DVD" link below.

For more information regarding and preventing this issue, please visit these helpful articles: Some info about .wmv files and MyDVD, Preparing DVD Files for MyDVD, Preparing VCD Files for MyDVD, Preparing Files For DVDit!, "Burn" Button Grayed Out, and How
much can I fit on a disc (DVDit! and all other applications).

I'd guess you recorded and compressed them at a low resolution/bitrate for your computer, but for any DVD authoring program to be able to write a DVD for playback on a set-top player, the resolution has to be bumped up to DVD standards......so, your 100mb portable file is now a 1gb TiVo sized file.

Also.......if you're converting them to MPEG-2 for playback on a set-top player, MyDVD is stripping the audio and creating an audio track that set-top players recognize, and depending on the bitrate you choose, that file size can be HUGE. At highest quality settings, you won't fit much on a DVD.

Yep....~65 minutes of full stream NTSC audio/video is all a 4.7G DVD holds.
