DVD disc compatibility btw computer and DVD player

My friend makes DVD of episodes he records off of TV. They play fine on his DVD burner/player in his PC.

When I borrow the discs, they frequently (not always) come to a grinding halt in my Mac (using DVD Player app). When I put them in my commercial, made-in-Japan Panasonic DVD player, they don't skip a beat. Well, to be accurate, they sometimes "artifact" (display those weird, large, square pixels on the display) for a few seconds, but never halt.

I just want to understand the difference between the computer's DVD player and the commercial one. Is it the software that is giving up and quitting? Or is it the hardware (the DVD drive) that fails.

To my mind, the DVD Player app could simply skip those sectors and move right along, displaying whatever jerky video it can assemble from the disc.

Is it true that another player app could play a marginal disc just like the commercial DVD player without quitting?

Thanks,

But of course you didn't, or else you'd not be cross-posting this to sci.electronics.basics, sci.electronics.equipment, sci.electronics.misc, sci.electronics.repair

At the very best, this only relates to repair.

But realistically it has nothing to do with the sci.electronics.* hierarchy. There are plenty of newsgroups devoted to computers, and plenty devoted to DVDs where the question properly belongs.

Many of the older model computer DVD players are not very compatible to DVD's burned on the newer players. This has to do with data write speeds, tracking accuracy, and the DVD type.

Personally, I would change the DVD unit in the computer to a new updated model.

When exchanging DVD disks, the DVD-R is probably the most compatible between drives and systems. Ask your friend to burn them at the slowest speed rather than ripping them off at the highest speed, as like many people do.

Michael Black: Oh, come on now, Michael..... there are plenty of regulars and visitors to this group sci.electronics.repair that can field questions such as DaveC posted. .... and I, along with many others will certainly take EXCEPTION to your statement that sci.electronics.repair that "at the very best, this only relates to repair" ...... just take some time to "read the mail" on this sci.electronics.repair newsgroup and you will soon realize that there is a lot of expertise in a lot of related fields including computers and DVDs.... and not neccessarily just repair. Let's not get your panties in a knot here. If you don't want to answer the question then don't waste your time with a reply. electricitym . .

I understand the Mac DVD player software is at fault.

Lack of compatibility is a common pronblem - Manufacturers from the two camps (DVD- and DVD+) argued for ages over who's system would produce discs that were readable in the largest number of drives. If you friend has a multi standard drive that will burn both + and - media have him try the other type.
