LG 4120b & Gigastorage 8x dvd-r medias

Does anyone know if the gigastorage medias are (GSC003) recognized by the lg4120b or if there is a version of the firmware that supports them? (Pionneer seems to support them but my burner refuses to burn them at more than 4x …)
Or can someone redirect me to another useful topic in order to patch this. thanks.

Well according to LG tech support the firmware that will be released on December the 1st (A112 official firmware) will have that fixed (the manufacturer code enabled…)
