Strathglass, welcome to the best forum in Canada.
In my opinion it’s best to stay native, without any re-compression, without transcoding codecs. Large hard drives are pretty cheap nowadays and getting larger and cheaper by the month.
There are programs that will copy a DVD into a mirror image called an ISO
. There is no generation (quality) loss in doing this.
If you really insist on transcoding and shrinking than I suggest transcoding to DivX
. Many newer DVD players will play DivX encoded discs and many home DVD authoring programs will convert DVD VOB files to DivX. But like I said – the best quality is not to transcode. Digital video and audio files do
suffer from generation loss unless copied bit for bit without shrinking or transcoding.
Be aware that you may run into copy-protection trying to copy your commercial DVDs.
Also, most commercial DVDs are dual layer (DVD9) 8.5GB
That’s my 2 cents.
