Hi: I burn my DVDs through V.Studio 7. Im getting a max of aprox one hour fifteen minutes of video on each DVD. Is this a matter of compression rate on mpeg2? How can I get more video length or time on each DVD? Modyfieing the compression rate? How can I do this? With a different rate of compression to record more video on each DVD...will this affect the video quality?
Thanks for all the help you can give me on the matter.
Jose.
¿Only 1,15 hour of video on each DVD ?

Compression
Yes, you are on the right track 
To fit more video onto your disc, you can check your project properties when creating your DVD project. Using a lower bitrate for your video will allow you to fit more time onto your disc -- but keep in mind as you lower the bitrate, the video quality also starts to go down.
If you are using lpcm audio, then switching over to something like Dolby Digital (AC3) or mpeg audio will give you more room for your video. But keep in mind that mpeg audio is not a standard for NTSC DVD Players, so some players won't be able to playback that type of audio.

Just something else to think about - it depends on the quality of your original video. If you are importing digital video directly, via firewire, then I agree with you; keep the quality as high as possible. I run home-grown movies/DVDs at a bitrate around 8000.
If you are copying or archiving stuff from VHS tape, the quality isn't great to start with; you can put two hours on a DVD (at a bitrate around 4000) and not notice the difference.

If you have source video that is of good quality then lowering the bitrate does not necessarily result in a noticably inferior end product. For example, if you are using DVD quality (8000Kbps) source video then reducing the bitrate to 5000Kbps would have negligable effect on the video quality whilst increasing the duration of your DVD. Of course, only you can decide what compromise you are willing to make as regards perceived video quality compared to the duration you can fit on a DVD.
