I'm using a Panasonic DMR-E30 to record some family videos but when I tune to L1, I only get sound for about 2 seconds with no picture and then the RF modulator shuts off and I get nothig.

Other than getting a TV with RCA jacks, does anyone know why this happens?

SIMA reps told me this should not be the case but there it is.

Any thought are appreciated.
