About CyberCom 4931 standalone DVD player, does play vcd/svcd/dvd and CD-R (CD-RW not tested yet). But it doesn't handle CD-R well, sometimes it gives sound-drops, or with (S)VCD coloured blocks appere just if those VCD is broken. Testet different qualities / writing speeds / CD-writers. Anyone same experiences or any tips to get rid of the problem??
Is there a firmware update available, anywhere???
