Yes, 1 star. Don't get me wrong, the CD itself is pretty much perfect and had I bought just the CD it would have garnered a 5 star review. However, I bought the CD/DVD combo and it is the DVD I am basing this 1 star review on.
I have two words for you - Aspect Ratio.
Who encoded this piece of crap? I understand that it is a Region 0 disc, so to expect a 576 x 720 picture is probably going too far and that the 480 x 640 ratio fits better on foreign systems. However, the idiot behind this disc has encoded the videos a 480 x 720 resolution. This means all the videos are squashed vertically (or stretched horizontally, depending on your thinking), ruining the look of them.
As if this wasn't bad enough, the producers, in their infinite wisdom, decided to make the DVD 4x3 (it's 2012 people!!) instead of widescreen. This is fine for the older videos (even if they are squashed), but it means the newer, widescreen ones are letterboxed, bringing their resolution down to approx 330 lines. Now, as anyone who has 'zoomed in' on their TV will know, this makes the picture quality drop massively. Zooming in on a 330 line picture on a big screen TV makes these videos look hideous! What they should have done, instead of making the newer videos '4x3 letterbox' is encode the DVD in widescreen and make the older videos '16x9 pillarbox', then they'd all look lovely.
So, in closing; Poor quality, low resolution, badly encoded and in an incorrect aspect ratio.
Save your money and just buy the CD and download her videos off youtube for free in the correct ratio and at the correct resolution.
