DVD Compression and Playback

[Taylor87]

Maybe someone can clarify something for me.

When using the re-author tool to back up DVD movie discs, you can take foreign sounds and subtitles out and save the amount of compression for the main movie and sound. I play discs back in my Xbox and PS2 and sometimes get the jittering freezes from time to time.

Does anyone know that if the compression percentage is related to the playback? If I take out the extras and have just the main movie, and the compression rate is less, will that effect the playback?

This has nothing to do with the amount of compression. Try using higher quality media...

Thanks for reply

I am currently using Fujifilm 8x DVD-R. Which brands are considered higher quality? I also have Memorex 4x DVD-R.

Take a look at http://www.videohelp.com/dvdplayers....y=Name&hits=25 for media compatibility with your Xbox.

Slow down your burn speed and avoid multi-tasking....

Ensure you are using the latest version of your burning s/w and latest firmware for your writer.

I use Datasafe media with the Ritek G04 dye burnt at x4 speed and my backups work flawlessly on both my PS2 and Xbox.

Compression Ratios

Mig$y,

are you saying that compression ratios have nothing to do with the quality of the final copy?

if not, can you please explain in which direction should a user move the compression level to achieve a higher quality picture.

thanks,

Hi KeizerSoze

I'm not quite sure how you have come to this conclusion after reading my post in this thread.

Applying compression will indeed effect the quality, whether you will be able to see any quality differences is a different story.

To achieve higher quality the compression settings need to be closer to 100%, the closer to 100% the less compression used with 100% being no compression.

Ahhhh!!! Thank you sir! Now I understand.
