IÂ´m using the iHBS112 for scanning, and my scans with 2x of Philips branded INFOMER30 look similar to DeanwittyÂ´s scans of HIDISC printable INFOMER30, so I wouldnÂ´t say these Philips ara not as good as HIDISC.
Maybe the scanner makes the difference.
I had trouble with LiteOn and Samsung BD-ROMs delivering irregular ODC scan results.
Now, using the iHES112, I get reproducible results.
Inspired by Your posts and scans (Thank You!), IÂ´ve ordered some HIDISC printable from Japan, hope to get INFOMER30 as well.
