if i was to rip my collection on to a hard drive and then to save space compress it into a winace archive file when i uncompressed it would the quality be the same or would it ruin the quality of the video in the files?

You probably won't get any space reduction from archiving it in that way. (Also I would recommed WinRAR over Winace)

You will find that the VOB files (that contain both audio and video tracks) will hardly compress (if at all!).

"ripping" them, which just means copying the contents 1:1 to your harddisk is one thing, but then you would need anywhere from 4-8 gigs per DVD (depending on the extra's menu's etc. etc.).

For 1:1 backups it is a very good way, but then there are 2 things to consider:

a) the space it would take on your harddisk (very costly!)
b) the fact that you would need to burn them on a dual layer DVD's in case you need the backup and would want a 1:1 copy.

Tools like DVD2One or DVD Shrink (or Nero Recode, Clone DVD etc etc.) will re-code the DVD to make them fit on a 4.4g blank DVD so that usually saves a lot of space.

Note that these tools never recode the AUDIO just the video. The quality is usually very acceptable (on a regular TV you won't notice a lot of difference).

Real 1:1 copies are currently only possible with dual layer DVD's and sometimes even that is tricky cause a lot of stand-alone DVD players do not recognize them!

Which means you also need to trick them into believing its a regular DVD by changing the media identifier of the DVD (when burning).

A fairly new method is ratDVD which does recode the sound too and makes files that are usually around 1.5-2 gigs!

But you will loose more quality in both sound and vision.

Bottomline: compressing them with winace won't save space. Recoding will, but will cost you quality.
