Standard Play (SP) is the most common recording speed used for VHS tapes, including rental tapes. You get the best quality audio and video when using the SP tape speed. Video conversions will be best from SP VHS tapes. Long Play (LP) is a seldom used format, and has been removed from many VCRs. Extended Play (EP) or sometimes (XP) is the longest VHS recording speed. You can get up to 360 minutes of recording time on a T-120 video cassette. This saves money but reduces quality.
