However I'm sure we should be able to get a lot smaller even before we start sacrificing quality, with better codecs. But I don't know what to aim for so I know when to be happy... any suggestions on Mb/minute I should be hoping for?

I do know that my Humax PVR can store HD TV at something like 1Gb/hour, and when I downloaded a F1 race I missed the whole thing in crystal clear HD was 1-2Gb so I'm guessing a ballpark of 250Mb for a 25min episode, maybe?

Last time I tried this I gave up and torrented the TV series instead. DVDs are at in a box on a shelf in my study still unused

This is the resolution of SD video as found on DVDs, DVB-x and DV (i.e. SD camcorder footage) although DVD and DVB can be lower resolution I think. The 576 comes from the # of scan lines that contained actual picture data in days of analogue TV.

Just in case it's helpful to anyone, I have ended up using 2 tools:

1)Use MakeMKV to obtain very high quality versions of the video files from the DVD. No options for quality, it just does it so I was looking at 2Gb/hr.

2)Use HandBrake to convert to something more manageable. I used the default profile to convert to MP4. I changed the main X.264 quality from 20->21 and applied a de-interlacing video filter on "fast" mode... without the latter it looked very liney for some reason. Reducing the quality meant 500Mb rather than 700Mb per 45min episode, from a 1.7Gb original MKV.

I was also going to try AnvSoft Any Video Converter but HandBrake worked pretty well so I never got round to it.

Zero bytes is the most optimal and not illegal if unwatchable...

What the law says, and what is right, are not always the same.

From memory (I'm not at home with access to my media server) the standard size of an standard definition program ends up being about 400mb for 40 minutes so yes 250mb for a 25minute program.

MKV HD is higher at about 1gb for 40 minutes.
