Zusammenfassung:	This invention relates generally to a method of recording video information onto an optical disc of the rewritable type. The invention relates to determining in real time whether errors were encountered during recording a physical sector and generating error sector information comprising a list of sectors wherein errors were encountered during recording. The error sector information is recorded on disc, preferably in VRMI user data to playback compatibility with standard players. During playback, error sector are skipped from reading. Advantageously, a buffer cell is created for information recorded in error sectors so that seamless playback is possible. Advantageously, when formatting the disc, the error sector information is not deleted. Advantageously, the error sector information is used to inform the user about the disc quality.
