Copy DVDs on Computer/external Hard Disc

Could you please help me identify righ kind of software which could facilitate copying DVDs (home made, music, movies etc) on my computer Hard Disc and/or external portable Hard Disc?

One interesting missing information is the format of the files and the type of output you desire…

For regular DVDs containing Video_TS and Audio_TS, CloneDVD2 is very good. The output is burnable on regular DVD-R.

If you want a diferent output format or your video content isn’t standard, check out, a universal video transcoder that works on most OS and has many output types (MP3, MP4, avi…).

Hope this helps.
