Just downloaded and tried that one (Exact Audio Copy)

Seems to work well apart from the fact it rips as wav first and then converts that to flac.
Now the stupid question

As I'm not too clued-up about all these different formats, will that result in an uncompressed file?
(You need to choose "compress" to get it to convert to flac or it stays as a wav file).

Sorry to sound dumb but I've always ripped at 128 mp3 but we are more demanding here now so, should any CDs go out of print, I'd sooner upload them in as high a quality as possible.
Oh, apparently, the problem with CDex is caused by a dud codec somewhere in the system (it checks every one). Of course, finding which one is dud will be no easy task

As soon as it finds it, it stops loading with the "CDex CD-Ripper has encountered a problem and needs to close. We are sorry for the inconvenience". Yeah, sure you are..............
