I bought a Sony DRU720A 16x DualLayer DVD writer recently. DOUBT ONE: The 1st 2 data DVDs i wrote with it gave huge errors... that too after takin lots of time... about 50 min. each... goin to 80% then hang... errors... The second DVD got burnt i suppose but DATA sector errors cropped up. I think it was due to negligible space of 1.2GB in my workin drive. So the third DVD i wrote as multisession of 1GB each. Three MSessions were done. The 1st MS went well... Then I did another session on the same DVD which also went well. The last MS i finalized the DVD.. but after a succesful writing.. the DATA verification gave me READ SECTOR errors... AND I LOST ALL THE DATA I WROTE IN THE LAST 2 SESSIONS.. ONLY THE DATA I WROTE IN THE FIRST SESSION WAS ABLE TO BE SEEN!!!! I used Nero... Ulead & Roxio for the three discs respectively.. and all gave similar probs.... The DVD+Rs were of TechCom, max 4X... Used Win98 and WinXP... Win98 for the 1st DVD... XP for the next 2.... Nero vs 6.6... OEM which shipped with the Sony DVDWriter itself I also wrote another DVD.... and then noticed that a majority of times... the errors crop up after finalizing the DVD. The files written in the final session are unreadable too. DOUBT TWO: How much time would it take to copy a DVD movie into a VCD on a PIII 1GHz 256MB SDRAM computer? DOUBT THREE: I have some Dual Layer DVDs holding 4-5 movies. I like some movies & want only those selected few... (2 or so) in a single DVD (single layer 4.5GB DVD). Is there some way I can copy those VOBs or so onto the 4.5GB DVD and play it on conventional DVD players... or is there any other easier & faster method... How much time'll will it take on the above said config? Does Sony 16X dual layer DVD writer ( I suppose it is a Liteon writer) read multisession DVD discs effectively?
