After checking it with other 80-wire IDE cable, on Master, Slave, Primary or Secondary channels, update MoBo BIOS, DVD firmware,etc nothing changed.
However, I installed Intel Application Acelerator as you tell me and I found the reason on IAA report:

...
Secondary Slave: HL-DT-STDVD-ROM GDR8161B
...
Firmware: 0102
...
Default transfer mode: UDMA-2
Transfer mode: UDMA-2
Transfer mode limit: Whitout limits
Cable type (device): 40 conductors (!!!)
Cable Type (host): 80 conductors
PIO PPE: deactived
UDMA control registration: Ultra DMA mode actived
...
(I translated it to english by myself so it's probably not 100% correct :P )

So it's likely my DVD-ROM it's inner limited to 40-wire...
Pity LG, or rather, Hitachi-LG (HL-...) sells an ATA-33, UDMA-2 capable device but limited to lower speeds by inner 40-wire architecture... :(
Notice that it's not so old, it's made on January 2003. Now I understand why it's not listed on LG's site.
Maybe it's time to change my usual optical-drive brand...
Thanks,
