Normally, if it is a bad hard drive that works intermittantly, then when it works and you rewind it, it will play perfectly not as you say with pauses in it. The pauses are caused by the reading of the hard drive but if it is happening in the same place every time you replay a recording then that was caused because the input signal was not constant and had a pause in it which was recorded because of the input signal and not the hard drive. If you have bad weather which causes pixellation, your recorder will record it and it will be like that every time you replay it. If you have a good recording but a hard drive going bad then sometimes you will get pixellation but at different spots or places in the recording. It may happen 2 minutes into the playback or 10 minutes or whatever and then the next time it may play fine. These are 2 different problems. I am wondering if your problem is caused by a bad input signal or a bad tuner.
