Hi ernstblaauw
The cdrdao version that Burrrn includes, is also the binary that is used with burnatonce, and which Gambit got permission to use from Jamie(burnatonce author). That binary is v1.1.7 with some code added by thop i.e. the "burnatonce extensions", which among a few other things primarily adds SPTI support which now newer cdrdao versions also support, but at the time of v1.1.7 didn't. Now the problem with changing the cdrdao binary out with a newer version, is that the SPTI commands has changed in the newer versions from the commands that thop implemented back in the day. This means that if you wan't to use a newer cdrdao version, then you will also need to untick SPTI and use ASPI instead(Just drop Nero's wnaspi32.dll into Burrrn's folder or anywhere in path; it is actually not an ASPI layer, but a SPTI wrapper that wraps the ASPI commands back to SPTI). Also you will need to use an updated version of cygwin1.dll, as the older one included in Burrrn most probably won't work anymore as it has been compiled with a newer version of cygwin and hence needs the updated and matching dll file also to run. The thing that you can easilly do though, is to update the decoding binaries from Burrrn's package like e.g. newer lame.exe and flac.exe versions. I would personally not recommend to update cdrdao to a newer version, since the newer versions actually dosen't add that much new anyways, and since any new functions implemented, you still cannot be able to use, as Burrrn isn't coded to utilize the new implemented commands. The only valuable thing that i can come up with at the top of my head, would be if using the generic-mmc-raw driver, which code for that isn't very optimized in v1.1.7, but gets about doubled in performance in v1.1.8, but besides that single thing, then there really is no reason or advantages to do so.
