CPU: 1.53 GHZ AMD Athlon 1800+
Memory: 768MB PC 2700
Source file size: 4.37GB
Resulting ratDVD file size: 1.13GB
Total conversion time: ~ 3.5 hours
Notes: Default ratDVD settings used. Source files contain video & audio movie only and no menus, no special features etc.
CPU: 3.2 GHZ Pentium 4
Memory: 2gb Dual Channel
Source file size: 5.62GB
Resulting ratDVD file size: 1.25GB
Ratio: 95 out of 150 (added this to see what settings ppl are using)
Total conversion time: ~ 3 hours
Notes: Full retail DVD used including all menu’s and special features.
excellent quality! definately the new wave of the future of sharing dvd’s.
one question, wesociety. What’s the point on making a ratDVD file if you don’t include extras? 
CPU: 1.53 GHZ AMD Sempron 2200
Memory: 192MB
Source file size: 4.37GB
Resulting ratDVD file size: 607,230MB
Total conversion time: ~ 5 hours
Notes: 8 Episodes of Friends on one disc done at maximum compression(40). Quality isn’t great though. Going to convert it back up and see if I can squeeze an entire season onto one 4.7 disc.
The re-converted DVD size is 2.54gb and the quality stayed pretty much the same - not good. It’s watchable if you’re not fussy, pretty much like a dodgy VHS copy, but it could be better.
Might try and see if I could run the re-converted DVD through dvd shrink and see what I get from that.

Quality is OK.
well found out last night that you can encode two dvd at once works great but thought you must have a high end pc to do this as my cpu running at 100% takes around 6 hours for both to encode.

X2: X-Men United (Widescreen Disc 1)
CPU: 2.0 GHz Pentium M
Memory: 1 GB (800 MHz)
Source file size: 7.37GB
Resulting ratDVD file size: 1.63GB
Ratio: 95
Total conversion time: ~ 3.5 hours
Notes: Disc 1 contains the menus, movie, 5 audio tracks (2 commentaries, 3 languages), and 2 subtitle tracks. I was also doing some development work in Visual Studio, along with other work-related tasks (e-mail, web) while it was ripping. Interesting note - it’s taking much longer (looks like it will take ~7 hours) to rip Disc 2, which is the special features disc. The size is 7.50GB, but I think the ratio of video to audio is much greater, and that’s making it much slower.
heres a nice detailed log of someones experience with ratdvd. http://www.p2p-zone.com/underground/attachment.php?attachmentid=9905
Movie : Harry Potter and the Chamber of Secrets
Original DVD size : 7.49GB
RatDVD file size (with 5.1 -> 2.0) : 1.44GB
Transcoded DVD size : 6.05GB
Quality : Default 95%
Follow screeshots of DVD generated from ratDVD file (note: ratDVD file was done with previous version of app, being readed and processed correctly by one)
Length of DVD generated: 4.27 GB
For comparing, follow screeshots from original DVD:
(The screeshots were captured with native tool from WinDVD and were compressed in jpg by one itself - I didn’t any interference as resize, compression quality etc)
I very like of results. It’s really amazing.
CYA!
To think i took some beating frome “Some Guy” in another thread in this forum just for suggesting to do what you “Brilliantly” did there with your screenshots danpos (and i did not find what he responded when i basically said for him to F&^k off).
judging from the screenshots… the quality is prety sh¡tty. Unless ratdvd does a better job I don’t think it’ll be a good alternative to DivX6, although it’s also true that DivX still have a lot of work to do so that the menus are as great as the ones in ratDVD.
The quality looks fine for me. Of course from the screenshots you can’t really compare to DivX, XviD because you don’t have the important details like bitrate, etc. I think in terms of video quality DivX, XviD, ratDVD are all on the same level but I prefer ratDVD to get the complete DVD.
But I agree that it’ll be interesting to see if DivX integrates menus the same way that ratDVD does. Sad thing is that they will NEVER be able to convert it back to DVD. And for sure I won’t buy another DVD Player only to get DivX menus (if this ever happens).
