Summary: My 300u has the same problem with the clean head message too. After approx. 30 min of recording and playing, "clean head warning" appears and blocks of noise appear during playback. This happened just last Sunday with a brand new unit. But came Monday everything seems to be normal again. Strange!!
Summary: This camera is small, nice looking, has good pictures, and cheap ($399 including freight). I was very happy. However, like some of the other users, it broke down after about 30 minutes of use.
Summary: Even though this camcorder has many great functions, I was disappointed that I had a dirty head warning after the first 60 minutes of use. Not what I expect after spending 650+. The recorder was new (sealed box). Trying to get the recording on a VCR is also giving me problems.
Summary: This digital camcorder brings Mini DV performance with a 680k pixel CCD and PCM Digital Audio for excellent picture & sound. Full DV connectivity, convenient LCD screen, plus a serial transfer cable and high value PC software package. But I think it should be cheaper.
