I have an XR 4500 system 5. I finally got the pvr working thanks to a download fron Buzz but it only stores properly on internal memory which is 10GB. I have a properly formatted 60GB USB stick for external. How do I transfer files(movies) from internal to external? The 10 GB fills up quickly (actually 7GB because of apps) and why doesn't the external storage work directly? When I use it, it only records 5 to 25 minutes and then shuts down or doesn't record at all. Should I use a 32 GB?
