The audio is coming out but the video is not coming when i play CD in the DCP750

Is this Wurlitzer designed with a screen to play videos? Has it played video CD audio in the past?
There are a lot of different audio/video file types and some CD setups will only play 'audio' file types, (MP3, AAC, M4A). If the file format is commonly used as video the electronics in the player won't recognise the format and won't play it.

have unit check seem like audio out put for cd an usb is bad;;

In most cases when the CD does not play it is possible that the optical head is a suspect. Sometimes it might pick up ordinary audio CD but will not play other formats. This indicates that the optical head is weak and so there is no detection or scanning of the CD . If the optical is working the tracks will be read immediately but with no scanning the laser head can be defective.
Sometimes certain cleaner disks will not be tracked to run for cleaning as it will not be read and so will reject. Hence it is ideal to manually clean the laser head eye using a cleaning swap /cotton bud with gentle pressure on the lens eye.
If there is no result then watch if the CD spins or tries to spin. If so the board seems to work unless a test is taken on the main board but the possibility of a defective optical head can be the suspected fault.
If any of the above seems otherwise we must recheck with possibilities of a malfunction of the main processor board

i have a durabrand portable dvd player model.pdv-709 and it will only play cds noy dvds

Australian players are designed only to play Region 4 discs. United States discs are Region 1. It is illegal to change the Region code on a DVD player, so I can't tell you how to do it (ironically, it is the most frequently asked question about dvd players on Fixya.com - global world), but there are videos on YouTube that will show you how to do it - I would just enter "philips region code dvd" as your seacrh term. You won't find that exact model, but one of the codes in the video should work. Note that you will only be able to change the region code three times on a Philips - after that you will be locked out. So change it to Region 1 once, and never change it again.

                in such case select "Video CD/DVD format" in Nero CD/DVD Burner


     for eg: "DATA CD format" is only storing some data on CD/DVD iresspective whether it is                            Videofile or Audio file, 

                these "DATA CD formated" CD/DVD when played in DVD Player will play only Audio files

I think you need the third party software to help play the dvd on ipod. Convert the dvd to ipod format first and then try to play the dvd on ipod.
