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.
