-   Very last things to know: of course, the PSX has the CDs in MODE 2... So the
-   common files are stored in MODE 2 FORM 1, the STR/XA files are stored in
-   "MODE 2" but actually they are in MODE 2 FORM 2. The MOVCONV tool will
-   in fact produce files that does contain the subheaders. And those subheaders
-   seems to contain a CN equals to 1, and the flags RT and Data are activated.
+   but it seems it's not very accurate, as you will se below.

+   Of course, the PSX has the CDs in MODE 2... So the common files are
+   stored in MODE 2 FORM 1, the STR/XA files are stored in "MODE 2" but
+   actually they are in MODE 2 FORM 1/2. The MOVCONV tool will in fact produce
+   files that does contain the subheaders. And those subheaders seems to
+   contain a CN equals to 1, and the flags RT and Data are activated for the
+   video frames, and FN, CN, and CI equal to 1, and the flags are placed
+   as it: RT, Form 2, Audio for Audio streams. So the Video frames are in
+   plain Form 1, and the Audio frames are in plain Form 2. But it _seems_ the
+   Video frames are not checked against ECC/EDC, but filled with zeros
+   instead.
    
    The last but not the least: the MODE 2 FORM 1 and MODE 2 FORM 2 are also
    called XA-Mode1 and XA-Mode2 or simplier: XA-1 and XA-2.
