The mosaic is often covering a relatively poorly defined area as it is. In the handful of games where the mosaic can be removed you're probably not going to be seeing as much as you might have hoped.
Explanation Using Pictures:

Fundamentally, there's no difference between most mosaics used in pornography these days and a solid black square. In other words, you can't decode them in reverse to restore the original image.
To appreciate this, I've attached an image with three different regions which I've mosaic'ed for you.
1. the right breast (which is on our left)
2. the left breast (on our right)
3. the right eye (on our left)
For #1, I applied a tame mosaic of 15x15 pixel-size squares and allowed for line splitting.
For #2, I applied a less considerate mosaic of 25x25 pixel-size squares, still allowing for line splitting.
For #3, I disabled line splitting and also made the size of each square 40x40 pixels.
Personally, I think #3 is the closest of the three examples to the mosaics you actually see in porn. And you tell me if you think it's even possible to look at that third mosaic and say, "Yes, with 100% certainty, I know what it originally looked like." I'm telling you: it's not possible to take that mosaic and get back to where we came from.[/hide]
Explanation Using Numbers:
[hide]Let me put it to you another way. 8. 8. 8. 8. 8. I've just said "8" five times in a row. But what if I told you that each of these eights came from a different origin?
1 + 7 = 8
4 + 4 = 8
3 + 3 + 2 = 8
2.79 + 5.21 = 8
-3 + 11 = 8
If I tell you the number "8" and then tell you, "Tell me where this 8 came from or I'll cut your balls off!", you're going to beg me for mercy. There simply isn't any way to know where it came from -- not with 100% certainty. You know where 4 + 4 leads, but you don't know where 8 came from.
It's the same exact thing with mosaics. You can predict what a mosaic will look like for a given image, but you can't predict what an image will look like for a given mosaic -- not when it's as crude as the ones used in porn.[/hide]

To make things clear, applying mosaics is a destructive method, information is lost and cannot be restored, even for single images.
The only "trick" to remove mosaics I've seen, is to apply a "resolution filter".
Once you know the size in pixels of your mosaics dots, divide the resolution of your image with the same factor. Then put the resolution back to the original value, applying it to the whole picture.
Now it doesn't look like there is a mosaic anywhere. Because the pixels size have been adjusted.
The result is that the image looks rather shitty, considering a 8x8 (or 16x16) pixel size for example (don't take 15 or 20 Sakun, everything goes binary there), this means the mosaiced area wins a factor 8 in resolution, but also the non-mosaiced will lose a factor 8 in resolution !
There is a website which describes this technique:

Nonetheless, the point is that hard-coded mosaics introduce irreparable data loss.
One final way to look at it: I set fire to three books. One is Jurassic Park. One is Doctor Zhivago. And one is The Divine Comedy with extensive appendices. I present to you one pile of ash. And I ask you, "Can you tell me which book this pile of ash came from?" I take a teaspoon to the pile of ash, raise it before you, and ask you a second question: "Can you tell me which words were formerly printed on the paper that constitutes this ash?" You might be able to if you were there to see it from the beginning. If you saw the book before I set fire to it, and if you knew what the book's contents were like (to the letter), and if you had the supercomputational skills of Ltnt. Cmdr. Data on Star Trek: the Next Generation, then sure, maybe you could pull it off. But the fact that you weren't there to see me burn the books means you're out of luck.
Mosaics do not merely scramble the visual data in a movie file around. If they did, then yes, it would be a simple matter of decoding mosaics to restore movies to their original format. Instead, mosaics are like fire: they permanently alter the data. And like the fire analogy, the only way you might be able to undo the damage of a mosaic is if you knew what the original movie looked like to begin with and could therefore try to figure out how, when, and where pixels were altered. But of course, if you already knew that, then you wouldn't be worried about the mosaic in the first place, now would you?
