DVR-108 Best X-Box Backup firmware?

What is the best backup X-Box firmware using the DVR-108?

Until I upgraded to the DVR-109, I used Piodata’s firmware v1.18 for the most part. However, Pioneer’s 1.19 worked flawlessly for me as well before the upgrade. Keep in mind, good media really counts for optimal readability from the Xbox. I strictly used Taiyo Yuden or Maxell made media with my Xbox.
