I am getting the following error when I try to open some ISO files with DVD Shrink 3.2: DVD Shrink encountered an error and cannot continue. Failed to open file "[my ISO file]". I'm wondering if there is any way to get past this error. Or is there another tool that will do the same basic thing without encountering this problem? I need to explain something about how I got those ISO files since I think it may be relevant to the situation. I downloaded a whole bunch of ISO files that were broken up into parts. The parts all had an extension like iso.001, iso.002, iso.003, etc. _or_ .par2. In most cases, the numbered extensions went up to about 334 and there were about 30 of the .par2 files. In a few cases, some of the files were missing from the download, just a small number of the files with the numbered extensions and a few of the .par2 files. In every case, I was able to join them all together with HJSplit but DVDShrink is not able to open some of them as I said at the start of this post. The odd thing is that some of the ISOs it can't open were complete and not missing ANY files. In other cases, they were ISOs that were missing a few of the files. This is why I'm not sure if the missing files are relevant or not to the DVD Shrink error. Now, I'm not expecting any miracles here. I would fully expect the missing files to cause some trouble. At the very least, I'd expect there to be gaps in the film as one scene or another never made it into the assembled film. I can live with that although I'd much prefer to see a blank screen for the duration of that missing piece that runs just as long as the missing bit of scene should have lasted. That would ensure that the subtitles would still be synched when they get to the next scene. Is that realistic, even if it involves some manual editing on my part? Or should I write off any ISO with missing files as being completely unrecoverable, even with gaps? I'm a programmer but I know very little about the file formats involved or the programs that combine, merge, or otherwise massage these files so I don't know what is realistic.
