2510a only sees 4x?

i have a 2510a with the 2A5C firmware, but i only seem to be able to burn at 4x. mostly i use cdburnerxp pro on win2k. i’ve tried 8x and 16x DVD-Rs, but after overriding the automatic detection and setting the speed to 8x manually, the disc can’t be read by my set top player after burning (philips dvp642). can anyone tell me what i might be doing wrong?

8x media should be ok for 8x burning.
But as your drive is an 8x generation one it doesn’t know 16x media, so 8x media is the better choice.
Try other 8x media, or try a firmware upgrade or a new drive…

hence my question. why does it only detect and burn at 4x?

:?:

What is the Media ID of the disks? Nero’s CD-DVD Speed , disc info tab , will give this.
