dvd player problems

[matt1562]

when i go to play a VCD on my standalone DVD player, i get an error that says unable to read disc. the disc has been properly sealed and cannot be written to again, all of the 3 files on it are all mpeg layer1. why will this not play on the standalone, but plays fine on my computer?

thanks, matt

Did you check to see if your dvd player is compatable? if not check the list they have here. Also for some reason when I burn my own, I will get errors some times or it just spits it back out, but if I keep putting it in it starts working. Go figure I don't know what to do to fix that, but maybe you should try that also, just my thougts.

PS: if anyone can help with my problem of having to put the same cd in like 5 times before it sees that's it's a vcd please let me know. I have a pioneer dv 414

[matt1562]

ok, thanks for the help. it sounds that your's is doing that because of a dirty lense. that happens to my cd-rom drive sometimes. i'm sure my player is compatible, and it's only a few days old. so if anyone else could help me, i'd be grateful

You are "sure it is compatible"?

Well, I'm sorry to say that it sounds pretty certain that your player is not. Does it say anywhere explicitly in your owners manual that your DVD player can read CD-R or CD-RW discs?

If not, your DVD player was not designed to read these media, and not surprisingly doesn't do it well.

Since your player is new, I would suggest that you return it and buy another DVD player that can read CD-R/W media if home-made VCD playback is important to you.

Otherwise, you will have to experiment with different brands of CD-R media to find one that works. Often CD-RW will work better in these cases.

Regards.

yes, the manual says that it can read: DVDs, VCDs, SVCDs, mp3 CDs and audio CDs. so i'm very sure it is capable of reading that type of media. when you say i should try another brand a media, i'm guesing you just mean switch from PNY to something like MAXELL, or SAMSUNG? thanks

Read my last post carefully. Your list does not include CD-R or CD-RW. VCD/SVCD/MP3 CD compatibility has absolutely NOTHING to do with CD-R/W compatibility.

matt1562,what do you mean .....all of the 3 files on it are all mpeg layer1. What burning software are you using and did you create vcd or burn it as data ?

[matt1562]

mpeg layer 1 is the same as an .mpg file. i have just used more of a complicated term for it. i'm using Easy CD Creator 3.5a, and i'm guessing from what u said that i'm burning the files as data, and not as a VCD. my dvd player also does not say it plays CD-R or CD-RW. but if done correctly i don't think the drive would be able to tell the differnce from my burned VCD from a real one. So i don't think it matters if the drive can play CD-R and CD-RW media or not. as long as it can play VCD and (S)VCD (which it can and is documented to)

Hey folks,

I got a LOT of confusion cleared up for myself by reading the DVD FAQ at
http://www.dvddemystified.com/dvdfaq.html#2.4.3

In short, what I got out of it is that DVD lasers area different frequency than CD-R and CD-RW. The FAQ has ***MUCH*** more detail!

I'd say that the post about trying different brands of CD-R might be a thing to look into, but more than likely, if you REALLY want to do this easily, read the FAQ, take the player back, and buy one that specifically supports/has a multiple frequency laser.

Different Manufacturers DO make their CD-Rs more or less responsive to different wavelengths of light.

Good Luck,
Bob

matt1562,
that's whatI suspect,that you've burned the cd as data,not vcd. bacause you won't find an .mpeg file in a vcd. you'll get a .dat file in it.
It's different between "burned" cd-r and comercially pressed vcd. Try different media and even try burning it in a cd-rw. (most likely the cd-rw will work)

@ matt1562,

The answer to your question has already been answered but if you persist with denying facts, no one can help you.

There is a massive difference between a burnt disc and a pressed one. Your explanation before justifying how they would be the same completely ignores the physical realities.

CD-R media were designed to be read by the infra-red laser (780 nm) of a CD drive. DVD drives use a visible red laser (630-650 nm) and at the wavelength, CD-R media do not work well. Thus, for a DVD drive to be able to read CD-R media, it either needs two lasers or a specially designed optical system catering for CD-R when it is detected.

DVD players that are designed for CD-R/W media will have this written in the manual separately. Again, CD-DA/VCD/SVCD compatibility have absolutely nothing to do with CD-R/W compatibility. All that means is that the player has the firmware to play CD-DA/VCD/SVCD when it detects such a disc (e.g., a pressed disc). It will play a CD-R version of it too if it can read the disc -- which would require CD-R/W compatibility.

Someone linked to the DVD FAQ further up this thread and a strongly suggest you read it. It explains in detail why a non-multiread DVD drive cannot read CD-R/W media well or reliably.

Regards.
