Yes, I had the same problems with my 708A.
It seems to burn some CD-RW discs ok, but then cannot read them back. For example, I had problems with some old Memorex CD-RW 24x and Princo 10x media.
Then I learned that 708A is just extremely picky with media, meaning that you cannot feed it with any quality media, only with
those brands that are on recommended list.
Before 708A I used LiteOn 48125S CD burner and I never even heard of problems regarding media compatibility, because this drive burns litarally on everything, thats why I was new to this kind of problems 708A introduced for me.
Now with my 708A I just use Verbatim DataLifePlus 24x (MCC) CD-RW high quality media, and all problems are gone, not even one coaster.
Also, latest firmware upgrade is highly recommended.
