Yes, another useful guide, 2COOL. However, as blutach also indicated in his reply, PgcEdit doesn't really blank the cell. PgcEdit only disables/kills the playback of the cell and instead plays the newly appended empty cell, whereas the old cell is still there in the vob. So this method is only recommendable if you're not after saving space on your disc. Otherwise VobBlanker is the tool to use, as it'll replace the cell with a blank cell. Don't you agree?
