Hi all, I have the 8300 HD. sometimes when I record something, it splits the recording into two files. for example I recorded a show last week from 8:30 to 9. this is a programmed recording set to record every week. when I went to watch the recording, there were two seperate recordings, 1 from 8:30 to 8:35 and one from 8:35 to 9pm. does this happen to other people? why does this happen?
