I did a lttle test with both options now. The "svcd" mode generates the
/MPEGAV directory, the "supervcd" mode generates /MPEG2 ...

The TRACKS.SVD contents are as follows:

supervcd:

ID [HEX] : 54 52 41 43 4B 53 56 44
Version[HEX]: 01
rsvd: 00
Tracks [HEX]: 02
Entry1[HEX]: 00 07 55 00 02
Entry2[Hex]: 00 15 35 00 02

svcd:

ID[Hex]: 54 52 41 43 4B 53 56 44
Version[Hex]: 01
rsvd: 00
Tracks[Hex]: 02
Entry1[Hex]: 00 07 55 00 02
Entry2[Hex]: 00 15 35 00 02

the image contains two mpeg2 tracks (two copies of the same 0:7:55 mpeg2
file).

seems it doesn't make a difference as far as TRACKS.SVD is concerned...
