Mosaic preview fails for some transponders. (Please the external attachment screenshot below.) However, for some other transponders it works fine and the codec dependency wasn't detected either.
DVBViewer v.5.2.8. Win XP x64 SP2. DVB-S2 card: PCI TwinHan 1041 (AzureWave SP-400).
(Since I have no space for attachment for 2-nd bug report, pls see the required detailed system info collection file in the topic/thread here)
