If I was to burn a Dual Layer Disc in a PC Burner would this play on
standalone dvd players/recorders (a recorder which doesn't support dual
layer writing) or would it be an invalid disc.

Seems to me that if dual layer recordable discs are worthwhile they must be
able to play on the majority of standalone players/recorders out there which
probably don't support dual layer writing - or do they only playback on
recorders which support dual layer writing.

Thanks.

Unfortunately most DVD players do not "explicitly" state recordable dual
layer support, so you are left to experiment and find out. This is a
similar situation to where we where 5 years ago, when no player even
admitted to playing single layer layer recordable disks, and again it was
left to trial and error to find out.

The only safe way is to play on a DVD Recorder, but then your disks won't
play if you take them somewhere where they only have a DVD player.

and I suppose its doubtfall that my dual format dvd recorder which doesn't
do dual layer discs will be able to read dual layer +R/RW discs... it'll
probably say invalid disc rather then read it - what do you think?

I bought a Panasonic DVD Recorder for exactly that this reason and it never
has a problem with dual layer disks created on my PC. But since they won't
play on ordinary DVd players I reverted back to producing double single
layer disk recordings and using a double disk case!

Considering that a lot of set-top players (which support pressed DL
natively) struggle with dye-based DL discs, you'll probably find a similar
proportion of SL recorders will struggle with writable DL discs.

They play on the ones they play on. Can't be much more help than
that I'm afraid. Probably not a good idea for general distribution.

Nick,

At a video bitrate of 6000 Kb/s and compressed sound (f.i. Dolby 2.0 at 224
Kb/s) you get approximately 1 hour and 40 minutes of excellent quality on a
DVD. Therefore, you might consider if you need DL discs at all.

224 Kb/s) you get approximately 1 hour and 40 minutes of excellent quality
on a DVD. Therefore, you might consider if you need DL discs at all.

P.S.: In MPEG-2 encoding do use a variable bitrate (VBR).

It's good advice about VBR - up to a point. There's often no need for VBR at
6mbps. Depending on your source, you should consider VBR when the bitrate
drops below about 4½. If you have exceptionally good or exceptionally bad
footage, or complex footage such as an action film, you might consider VBR
at such a high bitrate, but for a standard TV broadcast or (especially) DV
footage, encoding to VBR at that rate is a bit pointless.

It follows that if you're recording something that you haven't seen before,
you should consider VBR so that you're not caught out by the unknown nature
of the film. The problem with VBR is that it sometimes uses bandwidth for
non-important sections such as crossfades or fancy transitions.

Is there a compatibility difference between +R DL and -R DL?
