Hi rokas,
I did some test last week and everything works well.
I used: LG GSA-4160B DVD-RW (with the latest firmware) and
Maxtor DiamondMax 20 STM3160811AS SATA HDD.
I had no problems while burning from HDD to DVDs (both connected to Kama Connect 2).
OS: Windows XP Pro, SP2, most MS updates till 09.2007 are installed.
Btw: I created 7 DVDs (tried both DVD-Rs and DVD-RWs) max. write speed 8x.
