Cell commands

Hello,

if I specify conditional cell command such as "if (g0 == 1) jump title 1;", I get error
     ERR:  Cell command can only compile to one VM instruction.
But some other software (e.g. DVDReMake) supports cell conditional commands.
And I also didn't find this restriction at
     http://dvd.sourceforge.net/dvdinfo/pgc.html
Is it possibly a bug in dvdauthor?

Cheers,
Alex
