I was curious about something. I have a Panasonic DMR46vs and haven't really used it that much. I have been using -R media with good results. I wanted to record 2 movies on one disc and they are on delayed record about 1 hour apart. One recorded with no problem but the other one didn't record. I extended out the record time to 6 hours to make sure there was plenty of time. I had it setup to record one, shutdown then record again. I don't finalize until finished. Can you make multiple recordings on a -R disc or do I need to use -RW? Thanks
