Lessons Learned: Balky DVD Player

I have been following this forum with some interest, because I ran into an issue with a DVD I authored in DVDA 5.0 (not 5.0a). It is the most complex one I have done to date, 11 MPG2's (from Vegas 8.0c), all SD, AC3 stereo sound, a main menu and 4 submenus, lots of markers throught the 110 minutes of video.

Burned on Sony 16x DVD-R, printable, from Costco, with an Optiarc DVD RW AD-7190A 1.03, on a purpose-built Q6600 with 3 GB memory, 3 Sata Hard disks and XP SP2.

Whenever I am going to give away a copy of one of my masterpieces, I run it on four different DVD players, just to make sure. This project performed perfectly on a current Sony 5.1 Home Theater rig, a 2 year old Sony CD/DVD player, and a 3 year old RCA DVD that cost $39 at Best Buy. When it got to my 2002-era KLH DVD-8350, it would play (or not play) differently every time I tried it. I eventually figured out that my "Play First" mpg2 had a remote button configured for "previous menu" before a menu had been displayed, just as DVDA warned me. I fixed that but got no further than the first menu in an attempt to playback on the KLH.

Then I ran the image through a freebie program called VobBlanker which said I had problems in the VOB corresponding to the eighth segment (expressed in technical terms tat were way over my head). I had been working on this documentary for months, little and big tweaks here and there. I was preparing the DVD to a directory, and there were dozens of updates to that directory over time. I emptied the image directory completely, re-prepared the disk to the subdirectory, burned a copy and the KLH was happy.

But then, some friends came over with a still shrink-wrapped gift set of the first 2 seasons of Hill Street Blues on DVD. We fired up the KLH, watched Sgt. Esterhaus implore everyone to be careful out there several times, and went out to dinner. When I got back, I tried my DVD in the KLH and it choked on it. I powered the thing off for half an hour, started it up again, and the DVD ran great.

So I tried it again - Played more of Furillo and Joyce, and then tried my DVD - same result, wouldn't get past the first menu. Powered it off for awhile, tried my DVD, and it worked fine.

One of the DVD player aficiando sites says that this KLH was not intended to support DVD-R or +R, just pressed DVDs.

This all makes me nervous about handing out copies of my homemade DVDs to family and friends. They will have a motley collection of players of every vintage and quality, but I don't see that DVDA made me any problems, except maybe when I felt compelled to empty out the image subdirectory and start from scratch after all my edits of the input files. (No, I was not messing with the contents of the VIDEO_TS directory).

Here is what I take away from this adventure:

1. Pay attention to the warnings DVDA gives you
2. Do the burning from a clean copy
3. Run the image through the best analytic tool you can find/afford
4. Reboot balky DVD players when having trouble with a disk that works elsewhere

Those older players tend to overheat. It's really a common problem. Sometimes cycling the power works, sometimes you have to leave it off for a half hour or so.
With the price of new players so low, they're hardly worth hanging on to.

The first thing that will start to fail in an aging DVD player is the ability to play burned DVDs. The laser looses power and the lower reflectivity of burned media causes them to be the first to have playing problems. At times I've got a bit more life out of an old player by cleaning the laser but as said already these things are so cheap it's just easier to buy a new one. Even replacing the DVD drive isn't economically viable, assuming you can get the right drive.
