I don't write many CD's these days but wanted to put some mp3's on a CDR to play in my truck, since it plays a CD with *.mp3 files just as well as WAV files on an regular audio CD, and, of course has room for a lot more.
Going back to the FAQ on multimedia... What I noticed, was that after having made an iso of a "music" directory with some mp3's in it, using mkhybrid -R -o music.iso music Then checked I could mount them and see the contents ok with the virtual device. Then, after su'ing to root, cdio -f cd0c tao music.iso would fail after, say, 10 or 15% of the CD was written. Made a bunch of coasters then finally I tried cdio -f cd0c tao /home/myusername/music.iso and that worked consistently. What was curious for me was that I had the same result with both my 64bit desktop and 64bit laptop, and they were running 6.1 and 6.2 respectively. I guess access to a file is more efficient as an absolute path name, but it wasn't suggested in the FAQ, nor have I seen any such timing issues with writing CDs since long long ago when machines were a lot slower. Nor did a scan of all the emails in misc in recent years suggest such a problem had been seen by anyone. Well the CDR's are pretty old, but I went through a dozen not succeeding without that trick, and always had success when I used the absolute path name to the iso's.
