Combo drive reads commercial DVDs but not burned ones

Hi All:
I have an older G4 with Tiger 10.4.2 installed. I successfully burned a Video DVD, from a disc image, using Toast 7.0.1. My DVD burner is a Lacie external/firewire. The burned DVD plays fine in my stand-alone dvd player, and in my PC, but my Mac's internal combo drive just spits it out. The internal combo drive WILL play commercial DVDs just fine.
????
K.K.

this is likely because your external drive is burning DVD+r discs and the internal in your machine cannot read discs in that format. no worries though. get online and research 'bitsetting" or "booktype" modifications for your external drive. likely there is a way to bitset it to write to the universal DVDROM format.

Hi Steve:
Thanks, I will research that info. The burned discs are DVD-R however.

Could just be the age of the drive. If it's an original G4 500, then the drive is just a CD/DVD-ROM, as those models did not come with burners.

Blank DVD-R have a different reflective media than commercial discs, and older drives may not read some brands. You could try an alternate known quality brand of DVD; you could also try a DVD lens cleaning disc in the drive.

Final solution would be to lob the old drive & install a new DVD burner, which can be had for under $40, if you are in the US.

Hi Hussein:
Thanks for the advice. Perhaps buying a new burner IS the only answer. Since I have the external Lacie burner, which works fine, I wouldn't mind, for now, keeping the internal drive for read only...IF it could read the burned discs.
Here's the specs on the drive...perhaps it's just not capable of reading DVD-R or DVD+R discs???

Thanks for any more advice,

It should read DVD-R (some quality brands, anyway), but it won't read DVD+R.
