TEMPSTAR or Tempstar Records is a brand \ label name, which appears on 2 types of pirate products:
1) Audio CDs (Factory pressed - usually with "PD xxxxx" in the matrix number, where "xxxxx" is a 4 or 5 digits number)
2) MP3 CD-ROM compilations (CD-Rs with factory-printed artwork and surface design)

Audio CDs from this label are known for their unique artwork - very different from official versions of the corresponding releases. They are probably manufactured by the same company as makes MP3 Music Collection CD-ROMs (as both have similar "PD ....." patterns in the matrix numbers).

The MP3 \ CDr compilations under this label are manufactured and distributed by the same company as produces Digital Records (6) compilations.
