Hello, Ive just purchased a LG HR600 PVR but cant find any info on whether you can change the recording quality or not ? Can anyone tell me if this is possible please ? I would want to do this so that any recordings I make dont take up as much space on the HDD. Previous reviews seem to suggest that you can select between HD and SD recording but is this just a case of which type of channel you select to record from ? Many thanks.
