Occasionally i pick up an old title and it's on a purple dye dvd. As i was using reputable retailers i assumed all was ok. However, i recently picked up some ThirdWorldMedia dvds. They all came on purple dye discs but were no older than some others (machine pressed silver face) i had picked up from the same series. I did a check and found the purple dye discs all coming in at around 4.3GB. When looking at my machine pressed versions from that series they were all well above 5GB. I therefore assume these have been quite heavily compressed to fit on a single layer dvd+r. Do smaller studios do this, or am i looking at pirated copies?
Some studios used DVD-R discs for a while. Some ceased the practice, some still do I believe. So I doubt you got pirated discs if you bought from reputable stores.
Sir W, as far as I know Third World does not use DVD-R's. Can you let me know where you got them (by pm or email is fine)? Flash, in the UK we have seen many licensed sexshops sell pirated DVD's. Sometimes the store knows, sometimes they don't. Jacco
Oh, I know here in the states that Extreme Associates, VCX and Gentlemen's, among others, have used DVD-Rs at certain times. VCX even offered a trade-in for their DVD-R titles when they switched back to pressed discs.
Ok, I emailed ThirdWorldMedia and got this reply... Hello- yes, many of our older titles are being replicated in smaller quantities now on "purple" discs. If you tell me the seller name I can confirm if they are real dealers with legit product from us. I then asked about compression on the discs and got this reply.. HI again. The capacity of the purple discs is less. In some cases there may be slightly higher compression but it should not affect the quality to a large degree. I dont think you would see any difference between the purple and other pressed discs. Our new titles will all be pressed but our oldest will be burnt to purple. Hmmm....losing 1GB seems like a lot to me. Might get away with the 20% compression on a laptop screen, but on a large screen TV that would surely be noticable. Jacko...the retailer is in the top 3 of the ADM seller list. I'm sure they are fine...though i can't be sure whether they source dvds direct from studios or a third party? With the price of many films in this series (Little Asian Cocksuckers), they would not be worth pirating.

Do the purple dvds have the same amount of BTS, trailers, or other "extras" that the pressed ones do? They could leave some/all of that stuff out and not have to compress the main title to the extent that you're assuming they do.
A single layer recordable DVD has the same capacity as a single layer pressed DVD and a dual layer recordable DVD has the same capacity as a dual layer pressed DVD. So, they may be saying that they use dual layer discs for new titles and single layer discs for their older titles. Most companies actually did thia as dual layer discs were a lot more expensive in the early days of DVD and there weren't many replicators who worked with porn discs that pressed dual layer discs. For the most part, about 2 hours 10 minutes is the point at which you may see a difference in quality between a single and dual layer disc. Any disc that contains less than that is perfectly fine on a single layer disc.
The machine pressed discs are showing 5-6gb, so will all have to be dual layer in this case. I have tested 7, 8, 9, 10 and 16. The purple dyes are all at 4.3gb so i'm sure will all be single layer dvd+/-r's (they would not waste money on dvd-DL). I have tested 1&2, 3, 11 and 12. So a mixed selection from old to new. Comparing the two sets of films on a 37in TV, i can see some pixelation in the fast motion scenes from the purple dye titles. As some of the scenes are grainey anyway, it doesn't stand out too much. The average viewer may not notice it. Knowing it had been compressed i was.
Yes...they still have all the extras. The film would have been compressed as a whole. The fact they are all coming out at 4.3gb suggests they were shrunk to that size specifically. Longer films would suffer more than shorter ones.

It's even easier than that. If it's more than 4.3 GB of written data (or 4.7 GB of space on a raw disk), it's dual-layer. Just go to My Computer, right-click on the disk, select Properties and there's the info.

Old school, technique with no software or computer needs. You can also tell a CD-R or DVD-R capacity by seeing where the dye shift is. If the ring is in towards the middle and small, not much storage, if the ring is on the outer edge, lot more space. Old school visual.
...except it's no longer a reliable way of determining whether a disc is dual layered or not. Dual layered disc aren't always gold anymore. If you see a disc that is golden color, it's dual layered. If you see a silver disc, it can be either single or dual layered.
