when i go into audio on my cucosoft it says "output sample rate 48000Hz"it also says "audio synch"and it has a check box which i havent ticked which says "force to synch audio".i have the audio set at AC-3.i cant find anything which says PCM audio.

48 KHz is what's needed for dvd. But that's not the bitrate at which the audio is converted to. But AC-3 is fine.
Check if there's a maximum video bitrate.
If the bitrate is not the problem then either the software or the burning or the player is the problem.

How old is your dvd player? Are you using dvd+ or DVD- disks? Are you sure your dvd player can play both formats ok? Are you using 4.7 GB disks or 8.5 GB disks? Do you burn at maximum speed? What speed are the disks capable of & what speed do you burn at? Have you tried burning a DVD-RW disk 1st to see if that plays ok? You might try burning at minimum speed. Might also try a different brand of disk. It's difficult to put a finger on your exact problem. Disk skipping or freezing is generally either due to too high a dvd content bit rate, or the player doesn't like that brand or type or speed burnt at disk or perhaps the player itself needs cleaning.

maximum video bitrate is set to 9000.i have just bought my dvd player.i have got dvd-discs.my dvd player can play dvd+ and dvd-.i am using 8x4.7 GBdiscs at maximum speed.

Recommendations:

1. Reduce the maximum bit rate to between 8-8.3 (that's much!!! more than sufficient for catering for changes in movement between frames). It sounds to me like with your max set at 9 with ac3 & menus added on top it might be a bit much for your player to handle. I never have my max above 8.3, & I do outsourced pro work with video conversion, etc. Maximum bit rates at that high are only intended for very fast action & swift changes between frames & sections. eg: sports or high speed action. Normal videos are happy with a maximum well below 8.

2. Try burning your disks at minimum speed whatever that is. eg: 1, 2 or 4 speed.

3. Try a DVD-RW disk if your burner supports dvd-rw burning. Then after re-encoding at a lower bit rate see if the same problem occurs.

thanks very much for your help.that seems to have helped by reducing the speed.

Im sorry your right diddnt relize I was doing that not a good thing on my part but thanks for bringing that to my attention
