Date: Thu, 11 Mar 2004 18:45:17 +0900 From: Hayashi Naoyuki Subject: Re: Tru64 cdrom and pthread option fix I wrote /* Some CD-ROM drives cannot play the first 150 frames. */ in src/cdrom/osf/SDL_syscdrom.c and Some CD-ROM drives(ex. TEAC CD-532E) cannot play first 150 frames(aka gap). but this is not right. It is written in MMC that LBA = 4500*M + 75*S + F - 150.
