    They should be fine, but you only get 4.7Gb per side, so you will have to turn it over to get the other 4.7Gb!

    i.e. It is a double sided dvd-ram

    Thanks for your reply.
    I have found these DVD,s for sale at £1.74 on Amazon which appears to be a very good price or is there something I should be aware of?

    A quick Google search for LMHB94LE shows they are in a cartridge and unformatted, so you will have to format them before you can use them. It looks like they've been discontinued (one of the Google hits shows they were on offer in Panasonic's e-shop).

    The current ones, LMAD240LE, are pre-formatted.

    It should take less than a minute to format each side, i format my panasonic discs anyway, as usually i lose 2 mins recording time if i don't format them, per disc.

    Cartridge based dvd-ram's can only be used in panasonic dvd recorders, not players, unless you remove the disc from its caddy.

    (Remember its from Amazon Marketplace, so you will have to add p&p to the cost)

    If you know anyone who has a Costco membership, they sell packs of 10 panasonic 4.7Gb discs (non-caddy) for around £13.

    For a quick format, yes. But a full (physical) format will take at least 20 minutes per side at 3x speed.

    I use my dvd recorder (E55) - I have to format my verbatim dvd-ram's, & they have never taken more than a minute to do, they have *touch wood* performed flawlessly.

    I have found that the only virgin DVD-RAMs that I don't have to format are Maxell.

    I've found I have to format both Panasonic and Verbatim; this takes only about 20 seconds or so; on my E50 or E55.

    Strange.

    I've used loads of Panasonic DVD-RAMs in my E85s, single sided and double sided, and I haven't had to format any of them. In fact I've never actually used the format command.

    I can only suggest that all the DVD-RAMs both you and Delh68 have used have been preformatted and for some reason your machines need to quick format them before they can use them. I wonder if it indicates a problem with your machines.

    With Pannys, I don't know about other makes, you have no control over what sort of format is used. The E85 manual says

    "Some DVD-RAM are unformatted. Format them before using them in this unit."

    and

    "Formatting normally takes a few minutes, however it may take up to a maximum of 70 minutes (RAM)."

    A few minutes is a quick format of an already formatted disc, 70 minutes is a full format of an unformatted disc at 1x speed. So I assume that when a Panny is asked to format a disc it checks first to see whether the disc is already formatted, if it is, it does a quick format, if it isn't, it does a full format.

    As I understand it (correct me please, somebody, if I'm wrong): A quick format just clears the pointers in the file allocation tables, it doesn't overwrite the recorded data. So it only writes to a small part of the disc surface, which is why it's quick. A full format on the other hand, in addition to writing the allocation tables, lays down all the sectors, and marks any surface errors it finds in the process. So it writes to the whole disc surface, which takes at least 20 minutes at 3x speed or at least 1 hour at 1x speed.

    This applies to DVD-RAMs. You can't format DVD-Rs. If you could, you wouldn't be able to record anything on them afterwards! I don't know anything about formatting +/-RW discs, I haven't used them.

    Thanks for all the good advice.
    Tried to order 3 of the DVD,s from Amazon, they sell them in singles only so ordered 3 only to find the wanted £5 p&p each making a massive £15 for 3 disks incredible. Will check-out Costco.

    I usually get my DVD-RAM discs from aprmedia.com
    They're about the cheapest.

    I've noticed that Panasonic are selling the non caddy 10 packs for £19.99 but you get a 3 pack free with that, so it's 13 DVDs for that price.
    I've never had to format any Panasonics or Ridisc ones.

    Just make sure that these are Video Ram disc's as some RAM disc's won't work unless they say for video.

    I also have never formatted any of the Panasonic DVD-RAM discs. Also now have some Ridisc DVD-RAM's from Blankdiscshop (SVP). £14-99 for a spindle of ten.
