does anyone else having problems with ver 1-3 ps2 playing dvd-r backups?

[Kadawg]

is there anyone who is having problems playing backups of thier dvd rom based games onto dvd-r discs?.....all seems to burn good but upon playing it will play smooth untill it loads then its slow loading as well as glitchy....any suggests will be awesome...im using sony dvd-r discs and seem to be very good....all my cd-r backups work flawless
