Upper And Lower Filters

Question

I really have Easy Creator LE - Dell Edition, so I just chose EMC 8 as maybe about the same time frame, as my PC is from 2006. It uses XP.

I am looking for the values to set up for the UpperFilters and LowerFilters in the registry entry 4D36E965-E325-11CE-BFC1-08002BE10318. The Roxio Knowledgebase says to use RoxAssist, but it is not on my system.

I had problems before with the CD Drive letter disappearing, and I restored it by deleting the UpperFilters and LowerFilters. After that everything seemed fine in accessing the CD Drive, but I hadn't tried to use Easy Creator until now. I discovered that Easy Creator cannot find any Drive when I want to burn a CD. I believe it needs certain values in the registry for the UpperFilters and LowerFilters.

If someone can check the values they have for these filters and let me know, I can try them.

I have used successfully another program to burn a CD since Roxio did not work, but I would like to use Roxio.

 

Thanks

Thanks cdanteek and grandpabruce for your quick replies. I had thought that pxengine was for other problems, rather than the filters, since roxassist is for re-creating the filters. I ran pxengine remotely, but it apparently requires a reboot, and I don't want to reboot remotely, so it will have to wait for this evening to check if it worked. So far the filters were not added, but maybe this evening. I'll let you know.

Px Engine worked. Interestingly, there still are no filters defined for that key. It did add a number of files to \windows\system32.

 

You might be looking at the wrong GUID in the registry. There will be more than one instance of {4D36E965-E325-11CE-BFC1-08002BE10318} - in my registry there are 24 - but the one you want will start with "DVD/CD-ROM drives" when viewed in Regedit, like this:

It should at least have PxHelp20 as a LowerFilter now, else your Roxio program won't see the drive.

 

Cdanteek's link is for the most up-to-date PxEngine, version 4.18.16a.

Brendon,

 

 

Thanks. The only ones that apply are the ControlSet\control\class entries and really only the CurrentControlSet. You are right it does have that for the LowerFilters. Previously I always saw them at the bottom of the list of keys, but it was in the middle, and so I missed it.

 

I also have ControlSet001, ControlSet2, and ControlSet003. ControlSet001 has an UpperFilters of GEARAspiWDM and LowerFilters of PxHelp20 Pfc DRVMCDB DLACDBHM. The others have no UpperFilters and a LowerFilters the same as the CurrentControlSet.

Yes, I gave him the old one, which was used back when the older software was new. :) And, it still works.

It doesn't matter if the old version still works, 4.18.16a is the latest version.

 

Yes, it is the newest one, but it does matter if the old one still works. Cdanteek still lists it in his signature so, as cd said, we don't know which version sbruce45 used.

 

Had I seen cd's post, while I was typing my post yesterday morning, I would not have posted.

Yes, 001 is the prime set. Pfc, you have/had Disc Juggler installed? PxHelp20 is the one you just installed for Creator, and DRVMCDB and DLACDBHM are the filters from Sonic's DLA.

 

It's a busy little part of the registry. :)

 

 

Very interesting. I never had Disc Juggler installed though. Probably another program uses it also. Thanks for the info. Wouldn't it be cool if there was some place that identified what each program used. I also wonder what corrupts them in the first place such that the fix is to delete the filters, as stated in the Roxio Knowledgebase.

I used the one that cdanteek linked to as #7 in his list.
