Overview for NEC 5100/5500 firmwares ? Media questions

I could not find any info similar to the “Overview for different NEC (2500) firmwares” (from Liggy) - is there anything like that with the media strategy for NEC 5100/5500 ???

Basically I am interested in just a few things:

  • what +RW media can be well written at 4x (for the moment I could only find MediaID = PHILIPS.041 sold under Memorex brand)

  • what -R or +R media of a decent price can be used at 4x with 5100/5500 ?
