I have a sony blu-ray player and nero says i can make a disk that will be in HD if i make the disc with AVCHD . I have canon HD video cam and Vista with 2gig RAM .
At first i made some mistakes but now i can make the discs ok.
What i would like to know is when i make a disc alls fine till just before it comes to writeing to the disk and i get this massage "You are burning a disc with UDF veision 2.5 or higher. Windows XP and earlier veisions wil not be able to mount this disc" Can any one explain what it means. I just press OK and it works. Jack

Hi
AVCHD is a new format for video cameras recording method - these cameras (sony and panasonic at first) record to a SD card and guess some to HDD, and can do 1080i HD movie clips.
UDF is the DVD disc file system. It is used for a long time now and has some dif versions.
You can find this file system on CDRW discs and the RW versions of rewritable DVDs.
The warning you get is because some O/S may not be able to handle the versions that came to the market after their last update. If it works for you, that's fine. Otherwise you had to check if it is possible to use a lower version to do the job and if this version meets the requirements asked by your project/media/hardware/software.
As a new format blu-ray may ask for a quite new version, if you're going to record a blu-ray disc (that is not completly clear in your post).

Hi Thanks i think i understand. I am useing dvd datawrite i get 40 mim on a 4.7 gig disc. The player reads it as a blu-ray disk. I would like to get rid of this message as it stops the writeing of the disc as i have to press ok every disc i make. Can i set up a lower version of UDF. Jack

This is to inform you that older versions of windows will not be able to handle the disc. On your ystem, the disc will function as usual.
This is a email for Nero on the suject.

Ok, just so I understand, the footage is saved as AVCHD to a normal DVD and plays as a Blu-ray disk in the Blu-Ray player?
