Yes, it should support it, as long as you have a dvd drive in your computer to read the discs.

DVD RAM discs don't need finalised, hence its not an available option.

They will play directly on other players -*** BUT*** ONLY DVD

RAM players.

Don't expect your RAM disc to play on a normal

DVD+/-RW DVD +/-R device. Its not going to happen unless the

device supports DVD RAM also. If it does, it will play your RAM

disc once you've finished recording in your own DVD RAM

recording unit. Pop it out of your unit, straight into the other, and

the jobs done.

No, DVD-RAM disc recorded on the DVD Camcorder will not play back on every drive. Some of the new DVD-ROM drives designed to be compliant with the new DVD-RAM book2 standards will playback discs recorded on the DVD Camcorder. Many previous DVD-ROM drives on the market that came out before the DVD-RAM standard was released will not play back discs recorded on the DVD Camcorder. HITACHI manufactures DVD-ROM drives for some PC manufactures as OEM products. HITACHI model GD-7500 DVD-ROM has DVD-RAM read/write compatibility.

Yes. Although at the present time most DVD players only support DVD-R playback, Hitachi’s DVRF7U will play back both DVD-RAM and DVD-R discs. In addition, there is a growing number of affordably priced DVD-RAM players that support both of these formats. These devices make it very simple and convenient to enjoy the robust capabilities of re-writeable DVD-RAM discs.

Write Once – After finalizing, a DVD-R disc can be played back in approx. 95% of home DVD players and PC DVD drives Capacity – 30-60 minutes (depending on the selected filming mode) of high quality motion video can be stored on a single of a disc. Re-writeable – DVD-RAM allows for recording and re-recording of movies and still photos up to 100,000 times per disc. DVD-RAM is like a removable hard drive. Compatibility for video playback of DVD-RAM in standard home DVD players is fairly low. DVD-RW cannot store true .jpeg digital still photo’s like DVD-RAM, however it is re-writable and has 80% compatibility with home DVD players.
