    I just encoded my star wars -return of the jedi dvd, with DVDrb and HCEncoder (CCe caused my comp to restart like 5 times)I had Hc set on slow encode(high quality) removed audio, 56%quality 4 hours later I got a very pixelated copy, which is unwatchable, I get better quality from shrink with Deep Analysis. Did I do somthing wrong?? I thought dvdRb was suposed to give HIGH quality results?

    did you by chance use the freeware version?

    if so, be reminded that SW contains multiangle and the freeware does not encode those segments that contain ilvu

    i have done many sw dvds via rb and they are perfectly fine

    I used DVDrb .94 freeware, hc encoder free (suposed to be as good as cce) Does Multiangle increase quality? The very dark scenes looked like 10 blocks together.
    How close to the original did your copies get to the original, with menu?

    you're facing the following problem:

    the freeware version does NOT encode all those segments that contain multiangle/ilvu

    thus the average bitrate will have to be lowered quite notably in the other segments in order to reach the desired total output size

    this means you will have a totally UNCOMPRESSED segment when ilvu is present and in the following scene the encoder will have to drastically reduce the bitrate and apply heavy compression

    that's where macroblock might come from

    star wars should not contain that much multiangle apart from the intro sequence though but i can asure you my backups via rebuilder are just perfect

    so the question is: what is different with your encoding compared to mine

    i'm a pro user from the first day a pro version was released so i cannot tell you how 094free might look compared to the version i used when i did sw

    I don't think this DVD is multiangle.

    Did you change anything from the default settings? There are some AVISynth filters you could use to try to correct the pixellation, I think Deen is the one. Go into AVISynth options, and choose Filter Editor (I think that's what it is). Type in:

    Deen()

    This will increase the time it takes to encode, but may improve your output quality.

    I changed no default settings, and there are so many pixels even on a 27 inch tv. Im not sure if its normal on dvdrb to get pixels like that, as i use pinnacle instant copy 8.

    I can't speak for HC (although you're right that it's supposed to be nearly as good as CCE) but my DVD-RB/CCE Basic copy is excellent quality. Now that I think about it I did do some editing with DRM Pro to remove 2 out of the 3 sets of menus and turn the motion chapter menus to stills.

    I don't believe this is a multi-angle disc, and if it was I don't think the freeware version of DVD-RB would handle it at all (ie you'd just get an error). I know Episode I and Episode 2 had multiple angles for different languages, but I'll have to look at my originals for 4,5, and 6 to see if they do or not.

    what was the size of DVD-RB's output folder? Was it close to 4.4GB or so?

    maybe we have to agree on the terms a little better but i considered multiangle what you phrased multi-menu

    sw definitely does have multiple menus depending on which language is the default

    this way a certain amount of data may be wasted

    the freeware most certainly DOES handle multiangle and it does not produce any error

    like i said: ilvu segments are simply not being encoded - they stay as the come - and that may amount to a huge amount of uncompressed data

    Actually what I meant by multiple menus is that the DVD has 3 complete sets of menus, each of which is in English, and which one you get is determined by a random number generated from an IFO file. If you set the value to a specific value instead of letting it be generated randomly you can delete 2/3 of the menus.
    Guess that shows how long it's been since I looked at what's included in the freeware version ;)

    you're right, of course, multiangle/ilvu has not been possible to handle within rb in neither pro nor freeware version

    for quite some time now, the PRO does encode and the freeware version DOES not encode the segments but both handle the data

    but uncompressed ilvu segments will certainly result in rather inferior output quality and imho it is no good idea using the freeware version with any multiangle/ilvu source

    @daveerg, I would encourage you to purchase the Pro version ($10.00 donation) I like many have been using the Pro version for a long time and it is awe-some. I use multiplae encoders (CCE Basic, HC, and QuEnc) Never have a problem and jdobbs just released RC 6. Used it last night and the image is stunning for a 3 hr. movie compressed to a single layer Dvd 5. The installer makes it that much easier to use. Install, set it up and begin the process.

    I'm aware of what the Pro version does. I've been a contributor since around version 0.40 and have used every Pro pre-release. I just don't pay attention when features get put into the freeware version.
    In the case of the menus they use on Star Wars movies it doesn't really matter which version you use because it's not seamless branching or multiple angles. It's 3 completely separate sets of menus that operate independently from each other except for the fact that they're called by the same command based on different values of a random number. In any case, since menu compression isn't even implemented in the Pro version yet it wouldn't make any difference, and since those menus are several hundred MB each they can make a big difference in video quality.

    If I use RB freeware version but want to do all the editing with RemakePro, will this take care of this mulitangle problem I am hearing about? In other words, can if I use Remale Pro to edit with, will my v0.93 free version of RB be ok to use?

    @smg, there shouldn't be a problem. I have used Remake Pro to edit and then use the freeware version of RB to handle encoding and video file output. Now with the Pro version (v. 1.01 Final Release) I simply create an ISO image, and now with RB working with ImgBurn from Lightening UK it will burn the image automatically.

    DVDRemake has for a long time been used by members of this forum to edit before encoding with RB and the encoder of choice. That's over quite a span of the development. Though in most cases editing isn't necessary for a good RB output. If you finally have your Rebuilder app set up, it's time to start encoding instead of constantly asking "what if" questions. I realize you have a memory problem, hopefully you've started writing down some of these solutions for review.

    Your computer is restarting because your CPU is overheating. Is your system overclocked? If so either reduce your frontside bus or go back to default and try again.
