  First off... Tyler, thanks a lot for these handy tools/addons!
  A hint for users of this package:
  If you use makeudfimage, and you plan to use the result UDF image/disc under Win98, make sure you instruct the tool to generate images of UDF revision 1.50, because Win98SE doesn't undestand the default one this tool produce (revision 2.01).
  makeudfimage -r 1.50 /boot/home home.udf "Home backup"
  Now let's see if I can get (all of) dvd+rw-tools-6.0 working under R5 :-)

  Give v1.0.0 a try. There were a couple pretty serious bugs in v0.7.0 that could have definitely caused the problem you're describing.
  DVD-RAM support?

  I recently got my first DVD-RAM disc. It was formatted already, I can write to it in Linux and in Windows, but nothing shows up in BeOS. The disc name is correct but the directory is empty.

  It exists, at least:
  > Any plan to support it?
  As far as I understand it, Mt. Rainier support is something that would be done at the OS level, not the filesystem level. So we may support Mt. Rainier in OpenBeOS some day, and if so, then I'll probably add write support to UDF to take advantage of it.

  Well, I haven't been able to get DirectCD to work on my sister's computer, so if you could try to send me a disc image that'd be great. Here's what I would do:
  1. Create a new disc with DirectCD containing two small text files, each with a short, unique bit of text in them. For example, "Test file one" in the first file and "Test file two" in the second would be sufficient. Name them whatever you like. 2. Create a disc image in BeOS using the following command from a terminal:
  cat /dev/disk/ide/atapi/1/master/0/raw > ~/Desktop/DirectCD.img
  Your CD-ROM device might be named differently than mine, thus the "/dev/disk/..." path may need to be modified accordingly, but it ought to be something similar. cat will probably exit with some sort of error once it hits the unrecorded portion of the disc (I usually get a "device format error"), but that's okay, as long as the file it created is larger than 0 bytes.
  3. Zip up the image.
  4. Send it to me. You can either just email it to me, or if you'd rather ftp it to me, I can give you a server name and a login you can use. I would try the above on an unclosed disc first, and if it fails, close the disc and try it again. I think you'll end up with a fairly reasonably sized zip file, probably a few MB at most. If it turns out to be significantly more than that, then don't worry about it; I'll come up with another way to get my hands on a DirectCD image.
  Thanks a lot! Let me know if you have any questions or problems.

  How hard is it to get an image of a CD? If you point me in the right direction, I'll do my best to get an image - however if it's going to be 650MB, then I'll have to politely decline - I'm only on 56k internet!
  The CD I was trying with has probably been messed around a bit - ie "closed" to allow it to be read with iso9660, then re-opened to add more stuff to it. I'll have to give it a go with a simpler disk. My DirectCD CD burner's in the old comp, so next time I plug it in I'll have a try.
  DirectCD-type disks?

  Darn. Someone had mentioned InCD discs worked, so I'd hoped DirectCD discs would, too, but apparently not.

  Yes, I plan to support them by v1.0.0 if I can, but I'll need to get my hands on some DirectCD discs. My sister may have DirectCD on her computer, but if not, would you be able to send me some disc images?

  Re: Multisession discs

  > What about multisession discs?
  Darn, forgot to mention that in the readme. Only the first session is likely to work. Proper multisession support is in the works.

  As to each session being displayed separately, that's just how Tracker handles multisession discs for the time being.
  > Alas, your driver didn't seem to do anything at all.
  Well, it let you mount the first session, that sounds like a decent start to me. :-)

  I have a CD written using Direct CD. With the UDF add-on, I get a "General OS Error" trying to mount the disk.
  The disk can be mounted succesfully with the normal iso9660 addon, and I can see the disk contents, but all the files appear empty (0 bytes when copied).
  I know the last version specifically said it wouldn't work with Direct CD type disks, but that disclaimer doesn't seem to be in the docs for 0.6. Should the disk work with this version? If not, are you planning to add support for these type of CDs?
  Keep up the great OBOS work!

  What about multisession discs?
  I get a menu showing the title and icon of the disc, but it's multiplied by the number of sessions, and only the first session shows up when mounted, all the others are blank.
  Alas, your driver didn't seem to do anything at all.
  re: 0.6 test
  By Tyler Dauwalder - Posted on August 31, 2003 - 03:43:24 (#8633)
  I'm afraid I'm not very familiar with VLC. Why would one want to open a .VOB file? The only .VOB files I have are those found on commercial DVDs, and they open fine but play poorly (meaning the video and audio are all messed up) in VLC 0.6.2 with both iso9660 and UDF. Similarly, if I use the "File|Open Disc" menu, the discs play just fine (and load in a comprable amount of time), again with both filesystems.
  Are these .VOB files on discs you burned yourself? If so, with what program? It's possible that the larger files are using a type of allocation descriptor for which I haven't added support yet, hence nothing is happening when you try to read from them.
  As to performance, in my tests at least, UDF should be directly comprable to the standard iso9660 add-on. No faster, no slower. So if you have a hybrid disc that plays mp3s or whatever just fine when mounted with iso9660, but skips like mad when you use it with UDF, then something weird is going on. Otherwise, I think that sort of thing is acceptable for the time being. :-)
  mp3 frame drops

  The BeOS cache is very weak in this regard, and you can reproduce that behaviour with BFS as well - there is much fine-tuning necessary to play together with the cache perfectly.
  For example, my BFS implementation is still much worth than the original in this regard, even if it doesn't need more /(CPU) resources to do it.
  0.6 test
  By s_d - Posted on August 30, 2003 - 23:03:29 (#8631)
  tried it with VLC 0.6. Mounted and tried to open *.VOB.
  Short ones are OK. But with real long 1GB VOBs VLC seems opening it very slowly - couldn't open it on Duron 800 within 5 minutes.
  Tried also just to grab VOB from DVD to BFS. It started, but seems very resource consuptive - single MP3 playback drops permanently while tracker copies that file.
  By Tyler Dauwalder - Posted on August 1, 2003 - 00:13:43 (#8393)
  Most commercial DVDs are iso9660/UDF hybrids, containing both filesystems on the same disc. Thus, in those instances, using the UDF filesystem add-on doesn't gain you much over the iso9660 add-on. The real benefit will come when I get around to making a mkudf utility to create UDF filesystem images with BeOS attributes and indices.
  By jonas.kirilla - Posted on July 31, 2003 - 22:36:53 (#8392)
  Disregard my previous comment. The DVDs I've got seem to be in iso9660 format, at least according to 'df'.
