i did some goooggling in your problem mix and i found out that your problem mainly revolves around the slowness of the internet.
if you have a router, don't use it and directly connect the ps3 to the ethernet cable as bandwidth must be dedicated to the download. Dont download in the background and do those other suggestion just to make sure, but the main cause of this is the speed of the net as you are downloading a big file it cause to lag and files are corrupted in the proceedure.
Or try bringing your rig to someone you know that has a powerthirst connection that can DL large files at a short ammount of time.
