I bought the discs form Walmart, they only sell DVD-Rs now. I might have gotten some from amazon, but then I must pay shipping and that seems ridiculous for a few (10) discs. I use them for live images of various Linux distros mostly, I like being an explorer penguin (some people really don't like this, you see, it seems that most people who can't get something to work will give up, I report the bugs, if I have enough info). In Linux, you can actually study it all (kudos to Linux), vs., for example, with electricity, where you run into a big wall the moment you get into anything more complex then light bulb switches, or so I've found.

The hardware is either my laptop, which is almost 2 years old, and its build in drive, or my desktop, which I use PATA drives on, from a finicky USB adapter, or my new promise PCI card (which seems to not like burning DVDs at all (I'll have to debug this). I use the old drives because they still work, and seeing lots of good info about something scares me, there is no such thing as every XXXX piece of hardware on the market being perfect; now that I've been reading the thread: "new laptop: DVD or Blu-ray", I'm feeling much more enlightened. Can you point me to any particularly good sources where I might learn the differences between DVD+R and DVD-R. I know wikipedia is a source, but their material is not very in-depth most of the time, so I'll be doing several web searches and reading what I can find. FYI: I found the mmc SCSI docs here: http://13thmonkey.org/SCSI There is also an article about SCSI for the Linux kernel (with links) at https://ata.wiki.kernel.org/index.php/Developer_Resources Serendipity: http://gkernel.sourceforge.net/ thought it has no SCSI docs. And, there is always https://archive.org when a link fails you. Getting btrace working has become a bit of a problem as the new texlive-core-2014 package conflicts with dvipdfm (a dependency). I'll have to talk to the Funtoo devs about it. I'll start a new thread when I get some info. Thanks, David
