after burn path is changed

[Marek Nawa <mnawa@sst.pl>]

Hi,
I'm using  dvd+rw-tools 5.21.4.10.8-1ubuntu3 for Ubuntu. First session 
is allway burn correct. Unfortunately by other (merged) sessions I have 
strange problem. Output from run doesn't get any arrors:
growisofs -M /dev/dvd -r -root /test1/kopia_2006_18/kopia_2006_18_wtorek 
./kopia_2006_18/kopia_2006_18_wtorek
Executing 'mkisofs -C 146688,154048 -M /dev/fd/3 -r -J --joliet-long -v 
-relaxed-filenames -root /test1/kopia_2006_18/kopia_2006_18_wtorek 
./kopia_2006_18/kopia_2006_18_wtorek | builtin_dd of=/dev/dvd obs=32k 
seek=9628'

       use -input-charset to override.
mkisofs 2.01-unofficial-iconv (i686-pc-linux-gnu)
Rock Ridge signatures found


But when I mount burned DVD, after my root directory 
(/test1/kopia_2006_18/kopia_2006_18_wtorek) is additional subdirectory 
e.g "??PX$?mA" created.
It happens not allways but very often.
This new directory name hass always end with PX$?mA.
I haven't any idea why this stupid new directory is burned on my CDs. 
Could comebody give me some advice, what should I do for correct path to 
burn?
