No sound when I play back a commercial DVD

try cleaning the laser lense
If you have a dirty lense it can still read cd because data is not as compressed on dvd, each byte of data takes up far less space on a dvd so the dirty lense might not pick it up whereas it might pick it up on a dvd

This is common with DVDs which have been burned on a different, PC. The disk surface may be poor quality, or one of the drive lasers not aligned very well, or the lead-in track does not suit the player. If it is a commercial disk, try a few different ones to rule out laser problems in your drive, and if all OK, return the disk.

If you get continuing problems, the only economic course is to replace your DVD drive with a quality name brand one.

1. your device is not a 'DVD-ROM' device, nor a 'CD-RW/DVD-ROM' combo device.
2. you need software, such as the free 'VLD' software, to decode the DVD, and to "play" the video.
3. your DVD-disk is scratched -- will it play in some other computer or stand-alone DVD-player?

Hi,
Problem may be with your drive or playback software.

Solutions:

1. Copy your media from your DVD disc to your harddisc and then try playing it (not directly from DVD drive). If media plays well, then there can be problem with your drive.

2. If still play back jumps after copying the DVD to your computer, then the problem might be with your system. Download and install VLC media player from the link.This should fix the proper due to codec and playback.

I hope this is helpful in solving your problem.
Thanks

There are three options you can try: 1. download the DVD drive's firmware from the manufacturer and re-flash the drive's firmware, this will reset any region code in 99% of all DVD drives. http://www.ehow.com/how_2316521_flash-dv? 2. you can use software that, in realtime as you play the videos back, removes region code out of the file transfer stream from DVD to playback software. The best software to do this that I know of is called "AnyDVD". http://www.slysoft.com/en/anydvd.html 3. use region free DVD playback software like VLC, which is freeware. http://www.videolan.org/vlc/ The first option is the riskiest, if something fails while flashing the firmware, it could disable the drive, but it is 100% FREE. The second option involves buying software and making sure its running before watching any DVD's in the future. The third option is probably the safest, cheapest, and simplest for you. The DVD drive is not going to prevent playback of a region 1 or 2 movie if its set to region 4, its the playback software that makes this decision. If you rely on commercial DVD playback software or Windows Media Player, they will not allow the playback. VLC is region free, it doesn't even check the region the DVD was produced for.

Follow the procedure below to resolve the issue:

Step 1:
1. Click the Start button and then click Control Panel.

2. In the Control Panel window, click Hardware and Sound.

3. In the Hardware and Sound window, click Sound.

4. In the Sound Properties window, on the Playback tab, click to select HDMI and then click the Properties button.

5. In the HDMI Properties window, click on the Advanced tab.

6. On the Advanced tab, in the Default Format section, click the down-arrow next to the text-box and then click to select a sample rate and bit depth supported by the external HMDI audio device.

Step 2 :

Try installing the Updated version of the Video Driver.



Good Luck!!!!!!!!!!!!!!

Sounds like replacing the DVD writer drive would be worth a shot, quite a few issues going on there. I have not found a source for original drives other than used units which I would not recommend.

You may want to substitute the DVDdrive to point you in the right direction. WalMart sells an internal22x LITEON DVD Writer for $39, Bar Code 44149 00406 (others may not be IDE) that you can test or permanently repair with.

To test, unplug your ilo and simply:

1.Set the new 22x drive to MASTER (comes set as slave out of box, seetheir documentation or the drives cover switch legend markings).

2. If you wish to play commercial DVD's in your ilo, you must first install this DVD writer in a PC and play part of a commercial DVD. This will set the units Region Code. If you don't do this, the drive will not play commercial DVD's (it will not start or it will lock after copyright screens). If you don't wish to play commercial DVD's in your player, you don't have to do this step... it will play DVD's it creates just fine without it.

3. Take off the top of the ilo and move the flat data cable and the power connector to the new 22x drive.

4. Re-test all your issues. If your problems go away then you need the new drive. If not, the only other user action I can think of short of making sure all the cables are tight is to reload the firmware (http://www.ilohelp.com./download2.htm).


The new 22x drive can beinstalled in the ilo and, with some work, look just like the originalfrom the outside. Some other posts also say you can open a hole in thetop or back cover for the cables to exit and just leave the new drive on top ofthe ilo. Not crazy about that option but up to you.

Hope this helps. Good luck!

It can be several reasons
1. Disk is upside down
2. Lens is durty. You will need to use CD/DVD cleaning disk for that
3. Disk is having diffrent region code or recorded in diffrent formate (for instance player playback disk recorded in NTSC, and you trying to playback disk in PAL formate)
4.Disk is recorded at higher speed (for instanse player markered X16, but disk is recorded at X24)
Good Luck

By mentioning that your disks are finalized, I am thinking that you are not creating the DVD in the proper manner. For DVD's to play back on commercial equipment, they have to either be authored, created from a ISO file, or cloned, bypassing the copy protection imbedded in many titles. Do a Google search on DVD authoring or cloning to learn how to sucessfuly create DVD's that will play back on your home player.
