Maybe a struct to keep these two together, or a comment saying they
correspond to eachother 1:1

Can pkt->data ever be less than 5 bytes?

Not a huge fan of magic constants. Maybe just move the INDEX_DV* enums
to their own enum? Could use array index initializers to enforce that
they're indeed in the right spots in mxf_dv_*_uls[]. Combined with the
struct suggestion:
static const struct {
UID container_ul, codec_ul;
} dv_uls[] = {
[INDEX_DV25_525_60] =
{{0x06,0x0E,0x2B,0x34,0x04,0x01,0x01,0x01,0x0D,0x01,0x03,0x01,0x02,0x02,0x01,0x01},
{0x06,0x0E,0x2B,0x34,0x04,0x01,0x01,0x01,0x04,0x01,0x02,0x02,0x02,0x01,0x01,0x00}},
//...
};
