Why? The VOB's mastering should point to whether this flag should be set. In the meantime I found out that the main problem was that I made a full scan of the VOBs before processing them, somehow this confuses VobBlanker a bit. Probably the switches aren't so important, sorry. Michael

Hi, if I understand it correctly, ImgBurn holds a read buffer in main memory during writing an ISO file and it seems that it tries to write data from the buffer and to fill the buffer with new data at the same time. While this method is of course right when burning a CD/DVD, for creating an image it might be much faster to first fill the buffer until it's full then completely empty it (by writing only), then completely fill it up again (by reading only) and so on. If source files and the destination ISO file are on the same hard drive the frequent switching between read and write needs a lot of seek time. Michael

Thank you for your hints! Fixvts + dvdshrink did not work, dvdshrink refuses to read the data despite of fixvts preparation, but VobBlanker did the trick. As blutach described it, it removes the unused data from the titlesets resulting in DVD data of similar size (even a bit smaller) than the original hardlinked DVD. It is not even necessary to select any titles or cells to blank out, VobBlanker knows which cells are used by which titleset and removes the rest. If somebody with the same problem reads this: Differently from the default settings in VobBlanker - check "Fix always VOB SYNCI/SRI pointers in Titles" and "Fix ... in menus" in the "VOB internal pointers" section. - uncheck "Update STC discontinuity flag according VOB" in the "VOB layout" section. With the default settings I had a problem with the very first cell of the first title, it had a wrong length information. Michael

Hi, I want to copy a DVD which was created by a DVD/HD-recorder which sometimes creates multiple titlesets which point to the same data (e.g. "VTS_01_1.VOB" is the same as "VTS_02_1.VOB"). It does that when recordings with different qualities (more exactly different resolutions like full PAL and half PAL) are on the same disk, one TS per resolution. Unfortunately the direct copying by reading in the DVD as ISO file, then burning it doesn't work (other DVD-players read the copy without problems, but the recorder does not). Burning a new Video-DVD with the data of the old one does work (with some restrictions), but of course not with such double- or triple-titlesets which make a normal 4,7 GB DVD look as if it contains 9 or 13 GB. I know that ImgBurn can create such hard-links for data DVDs with identical files, but for Video-DVDs it seems not to work. Any hints what I can do? Thanks! Michael
