Q: How do I burn CDs instead of DVDs?
A: Just set CD/DVD size to 650 or 700MB, TkDVD will use cdrecord to burns files.

Q: When I try to burn files with a size > 4GB on a DVD, they are just ignored/not burnt OR I get an error?
A: cdrtools and older versions of cdrkit doesn't allow to create ISO image containing files > 4GB, they just ignore theses files. Just a little more recent versions of cdrkit return an error for theses files and don't waste your DVD that way. And finally, really recent versions of cdrkit allow creating ISO images using UDF filesystem when they contain files with a size > 4GB (see the man of genisoimage and particulary the -allow-limited-size command line option).

Q: TkDVD does not work under FreeBSD?
A: Unlike Linux, under FreeBSD 'tclsh' and 'wish' (TCL/Tk interpreters) are not symbolic
link to tclshX.Y and wishX.Y (X.Y representing your TCL/Tk version) but a strange script
that says tclsh can't be a symbolic link because of some obscure reason (from what I have read,
it may solve some problem but causes other) so you need to replace ' exec wish "$0" "$@" '
at the second line of TkDVD.sh with ' exec wish8.4 "$0" "$@" ' (or 'wish8.5' if you have
TCL/Tk 8.5).

Q: How to burn a DVD video using DVD-Video compliant UDF file system option?
A: You need to add the folder containing the VIDEO_TS subfolder of your DVD-Video.

Q: DVD-Video compliant UDF file system option doesn't work?
A: Try updating cdrtools and see above question.

Q: TkDVD doesn't format my DVD+RW
A: It's necessary to format DVD+RW media only if they are virgin. growisofs re-format
DVD+RW on the fly when you try to write new data on it.

Q: How can I add my own langage to TkDVD?
A: Edit src/internationalization.tcl and read the first lines

Q: Why do I get garbage instead of "special" characters in the interface?
A: It seems that default charset should be the same as the src/internationalization.tcl file, so if you get garbage instead of "special" characters, try to switch to UTF-8 in your distro/OS (slackware and slamd64 fall in this case, debian is already defaulting to UTF8).
Or you can change the character set of this file using iconv to match your distro charset:
iconv --from-code=UTF-8 --to-code=ISO-8859-15 src/internationalization.tcl > src/internationalization-new.tcl
That's an example to switch the file to ISO-8859-15 charset. Then replace src/internationalization.tcl with src/internationalization-new.tcl.
