Ah, but it will check the iso file.  What I do is download the iso, then
check the md5sum.  If OK, I burn it.  So far (keeping fingers crossed),
my burns seem to be either successful (the majority by far) or produce
an error message.  

And, if you are downloading a Linux distro to make your first Linux
installation, it is hard to do in Linux.

And, if you are paranoid, after burning a distro in Windows and
installing Linux, you can then check the md5 of the CD under Linux. 
(The one time I tried this, it didn't work.  I suspect it was because
(as I found out later), the CD must be unmounted to use md5sum
/dev/cdrom, and I think Linux (Mandrake 7.2) has afs or automount
installed by default (or I installed it without thinking about it).)
