Besides the standard set of media used to determine the write performance of any given DVD writer, another mode of test we conduct for a comprehensive assessment of DVD writers is to feed the drive with all available media at point of testing to get a better overview of media compatibility. Understanding a drive's media compatibility is especially important for anyone looking to purchase a writer. In addition, we can also determine the brand of media that would allow 'OverDrive' or 'OverSpecification' writing. Since the media used in this section are used on a basis of availability at point of testing, formal write comparisons between drives will not be made here. Since the LG GGW-H20L has the specifications of a typical 16x DVD writer, Blu-ray and HD DVD support notwithstanding, we have tested it with our usual selection of DVD media.

16x DVD+/-R

  • Sony 16x DVD-R = SONY16D1
  • Sony 16x DVD+R = SONYD21
  • Maxell 16x DVD+R = RITEKF1
  • Fujifilm 16x DVD+R = PRODISCR05
  • Maxell 16x DVD-R = RICOHJPNR03
  • Fujifilm 16x DVD-R = PRODISCF02

8x DVD-/+R and DVD-R DL

  • Verbatim 8x DVD-R = MCC02RG20
  • Verbatim 8x DVD+R = MCC003
  • Verbatim 4x DVD-R DL = MKM01RD30

In terms of writing speeds, the GGW-H20L was competent and did about as well as any typical 16x DVD writer. Like the GGC-H20L however, it was unable to write to the Maxell 16x DVD+R at its maximum 16x speed, so consumers who are considering these series of LG writers may not want to purchase this particular brand of media. The GGW-H20L was also unable to write the other dual layer disc we tested, the Verbatim 4x DVD-R DL at its rated speed. Taken together with our earlier test, we have to wonder if dual layer writing is a weakness of this drive, though two examples are probably too small a sample size.
