    The Recordable DVD Council is taking action to promote producers to make products DVD-RAM compatible:

    It's also good to note that DVD-RAM and DVD-RW move closer together. I think, as a whole, it will benefit the consumer no end if all recorders become DVD-RAM, -RW and -R read/writeable.

    Excellent news indeed! Lets hope new players will support the format more.

    Can't say I'm surprised Philips aren't on that list but disappointed that Pioneer & Sony are missing.

    Arguably it is somewhat significant that Daewoo and Cyberlink (both cheap producers of upcoming DVD+RW products) are signed up to this scheme.

    Pioneer have already added support for .VRO file format to their upcoming players - whether that extends to RAM playback (which requires a different laser setting from the default DVD-Video/-RW one) remains to be seen. Given the increasing ties with -RAM and -RW it is a possibility. Panasonic (or rather Matsus*ita) is Sony's greatest competitor so the latter will never, ever support DVD-RAM (which is unfortunate).

    In an update to this story it seems the RDVDC is now going to be conducting compatibility testing of the official formats:

    http://www.cdrinfo.com/Sections/News/Details.asp?RelatedID=4035

    Good news for consumers as we will get precise input on whether recordable and re-recordable disks will work in each player etc. Granted this already exists in the form of www.dvdrhelp.com but an official guarantee is always nice.

    As I briefly mentioned in one of the other posts JVC has launched two new PAL Progressive Scan DVD players capable of playing DVD-RAM disks. The model numbers are the VA-NA77 (RRP £160) and the XV-NA7 (RRP £250).

    Hi

    Adding DVD-RAM playback support costs more money than just adding VR support. While any DVD loader unit from any OEM will support DVD-RW playback, DVD-RAM requires specific hardware support in the loader.

    Yes DVD-RW VR support also requires extra memory and additional firmware and testing, which is why it isn’t on ALL DVD players to date, but DVD-RAM adds the extra cost of sourcing DVD-RAM supporting loaders on top of that. This also ties the manufacturer down to fewer sources, which isn’t good for procurement or pricing.

    On the other side, there is no excuse for a DVD-RAM recorder or DVD-RAM player not playing DVD-RW VR mode discs, as the loader will playback DVD-RW, and the firmware is already there for the UDF support and VR application layer (DVD-RAM and DVD-RW record using the identical application layer). Any DVD-RAM player or recorder that refuses to play DVD-RW in the VR mode is due to political reasons.

    Recent reports of the various manufacturers and promotional groups coming together on DVD-RW/DVD-RAM to harmonize the hardware and compatibility is happening too late, they were suppose to be doing this some 18 months ago under the logo of DVD Multi. If the recent reports are true that extra effort is now being put in place to standardise compatibility, then we should see these products emerging some 12 months down the line; in the meantime a lot of DVD Players will be sold with a confusing array of supported formats.

    Why are they saying they are sorting this out now, when it was sorted out months ago? They mention of more logos to advertise support for DVD-RAM. This boils down to Panasonic not being happy at the use of the DVD Multi logo, as they want to see DVD-RAM specifically advertised on hardware using its own logo. I expect Pioneer is the same in wanting “RW” shown on the hardware too. These manufacturers just do not help themselves do they. Throw into the mix logos for HiMAT (like the average consumer will ever have chance of understanding this along with the dozen or so other logos) and you can understand why +RW is doing so well despite being unreliable and lacking in features.

    Announcements today of these manufacturers coming together to offer some convergence and compatibility is just the stable door being shut long after the horse left the stable (probably died of old age by now). These announcements are not positive, just reactionary to competition from other formats and each other. It gives the message to consumers that DVD Forum recordable formats are still a mess and they need sorting out, and to not buy now but wait until there is some agreement!. DVD Multi is what they should have as logos on their players, not talking about new ones that will appear, perhaps sometime in the future!

    Just another viewpoint.

    Regards

    Philip

    I agree with what your saying PhilipL - in that it would have been nice if existing DVD players had long since started to be 'DVD Multi' compatible. The responce to this from the various conferences and fairs I attended is that the DVDR market here is still regarded in it's infancy - therefore compatibility will rise over time. The Panasonic and JVC players are essentially 'DVD Multi' players - similar units from Toshiba and Hitachi will follow next year and it therefore follows that the smaller companies will follow suit. Thus 5 years from now (approximately the half life for the DVDR formats) the compatibility will quite reasonable.

    Also most of the producers see the situation where the DVDR market 'explodes' as it has done in Japan and is doing in the US. When this happens compatibility will become even less of an issue as odds are DVD-RW and DVD-RAM will dominant like they are in the US and Japan.

    Exactly the same initial 'lack of backwards compatibility' will happen with BluRay. We will see the first BluRay units on sale here within 24 months and, although we are unlikely to see an aggressive reduction in price like with DVDRs, they will have no more compatibility than DVD-RAM when it first appeared! Overtime it will change.
