Hi Brendon
Alas, no change with my "no supported cd-recorders" condition.
For the record, this is what I carried out...
Located TS-H492A value related to device068 for HKEY_LOCAL_MACHINE\SOFTWARE\Adaptec\Adaptec Shared\CDEngine\Devices1
Amended it to "TSSTcorp CDW/DVD TS-H492B,TSSTcorp,CDW/DVD TS-H492B,MTK4832_Liteon,cdrmmc.drv,155,,9"
Also located TS-H492A against 3 other keys but left them alone for the time being.
Rebooted PC and tried ECDC.
Amended the 3 other keys to read TS-H492B:-
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\pwd_2K\device742\Parameters PARAM1 = "CDW/DVD TS-H492B"
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet003\Services\pwd_2K\device742\Parameters PARAM1 = "CDW/DVD TS-H492B"
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\pwd_2K\device742\Parameters PARAM1 = "CDW/DVD TS-H492B"
Rebooted PC and tried ECDC.
Short of trying it with another CD Writer (which I don't currently possess) I think I'll source a later version of the software. Meanwhile I am still able to use Sonic's RecordNow! (Which, just to make sure, I checked was still working after the changes.)
Many thanks for your assistance.
Rick
