I have many movies on VHS tape that I would like to put onto DVD's. I go into video capture in Roxio 8 and it captures fine, but whn the movie is done ( 1 hr 30 min.), it has taken up 25 gb of my hard drive. What am I doing wrong.  Help

Doesn't sound like you are doing anything wrong. DV AVI uses about 13GB per hour.  You could capture as MPEG, but it isn't recommended if you plan on doing any editing.  You need LOTS of hard drive space to do video editing and best to have a second hard drive dedicated just for that.

Thank you for the response.  I don't plan on doing any editing.  I already burned 2 movies onto a dl disc. and it was full.  I thought I would be able to put more than 2 regular movies on one dl. Any other suggestions.

Thank you
AJ

To get more on a disc, you must increase the compression or reduce the resolution.  Here are some guidelines:

(720 X 480 @ 9mbps): 64 minutes Est = 4,661.1mb
(720 X 480 @ 8mbps): 72 minutes Est = 4,675.4mb
(720 X 480 @ 7mbps): 82 minutes Est = 4,677.4mb
(352 X 240 @ 4mbps): 140 minutes Est = 4,669.1mb

Double Layer gets approximately twice the times listed about. You can also squeeze a few more minutes on a disc by dropping the audio to AC3 128Kb/s.

Hello again:

I did look into the different ways of compressing. One thing I didn't mention was that I have all-in wonder 9000 pro on my computer which is my capture card when I capture my movies. Would that make a difference?
Thanks

The software that comes with the ATI card may have more compression options. However if you do ANY editing, then MyDVD will want to re-render the entire file.  If the added ATI file is DVD compliant, then MyDVD should not re-render it if the file will fit on the disc.

What do you mean by re-endering?

[ggrussell]

Render does two things: it can convert one file format to another and will compress the file sometimes, too.  For example, capturing from a digital miniDV camcorder, the results is a DV AVI file which uses very little compression so the files are huge.  A DVD uses MPEG2 only so the file must be 'rendered' to MPEG 2 before it can be burned. This can take quit awhile due to the amount of compression. If the file has been edited, then that can also add to the rendering time. Stuff like transitions, overlays, text, etc.,  add more time to the rendering process.

If the files from the ATI software are already MPEG2 and DVD compliant, then MyDVD may use them without any further 'rendering' .  It just changes the file to the appropriate .VOB files.  There are a lot of  'ifs' for this to work correctly, but it does work.
