Juggle, I had some issues with recording replays this weekend(SD card got corrupted somehow, so i couldn't record replays), so what I'm going to do at this to prevent that is record the matches live like I used to before infinite replay existed to prevent that from happening. My recording setup itself has a flawless record; this screw up was because of the SD card itself, a step that can be completely circumvented. Basically my setup records straight from the tv to a USB flash drive, where it can then be immediately saved on a computer.
I will ask people on my setups to save the replays as well, that way I have a double security net in case one method fails. If everyone else doing brawl can have infinite replay on/do live recording at the same time as a double safeguard, please do so!
