First problem, note that although you requested cdrecord you actually 
got a forked and hacked version called "wodim," based on an old and 
obsolete version of cdrecord. It is linked as cdrecord to make you think 
you have the real thing, but you don't.

Your choices are these:
  (a) use growisofs
  (b) download and compile real cdrecord from
      ftp://ftp.berlios.de/pub/cdrecord/alpha/
  (c) use cdrskin

The (b) option will install in /opt/schily/bin, and requires running as 
root or setuid root, because the program uses vendor-specific commands 
where needed and the kernel blocks them. I install the real cdrecord as 
CDrecord, in /usr/local/bin, setuid root. That reminds me it's not the 
Fedora hack.

I find (a) easier to use in many cases, and (b) to work with a few more 
burners. I only put (c) last because I haven't used it much, since only 
cdrecord supports the features needed to burn SVCD video disks.
