I am having the same problem with Easy VHS to DVD for Mac (Rev E). I am running 10.7.5 on my Mac and for the first few transfers I had no problem after I figured out to not plug into the USB port before booting up the program. Now, the transfer goes for 15-20 minutes and I lose audio. The frustrating thing is I don't know it because I can hear the audio for the entire transfer and only find out when I review the flattened movie. The small "transfer device" does get warm while it is in operation if that helps. Any more knowledge on why this is happening to users?
