Great value, so good as to overlook all other bad points. Works great multi region, but I would recommend changing to the specific region every time you change, rather than leaving it on region 9, as this causes some reading problems.

I bought a United DVH 3161 some months ago.
It worked perfectly.

After about 2 month, a strange behaviour appeared and did not disappeared.

Everything is working fine except that sound is very low when reading a dvd or cd. I have to set the sound at the maximum level to only hear a weak sound.

But if I set the device on radio mode, I can hear the sound as before.

The problem seems to come from de reading of the disc. Maybe it is due to the digital/analog converter. Or maybe from the soft running.

Did someone face the same problem? Please let me know.
