I just found out that the lastest Sonic RecordNow DLX 7 installs pxengine 220.127.116.110. That is quit a leap from the 507 thats posted in their updates section. I can’t remember but I believe the 507 was 1.6.xx.507. I’ve noticed that with this update RecordNow Max 4.5 and 4.6 will show newer burner’s burn technology such as “seamlesslink”. It wouldn’t show this before. The same applies to burners using newer firmwares. Before RN Max would show 7.9x as the burn speed, but now shows 8.0x.
Don’t know if anything is really better than 507.
I would post the needed dlls for this newer pxengine but its probably not legal.
