Recovering video from trashed DVD+RW using EMC7.5


MartinW

Question

I have two DVD recorders that I use for off-air capture, a Panasonic DMR-EH75VS and LiteOn LVC9015G. Recently I had to have the Panasonic repaired and decided to record off-air with the LiteOn using DVD+RW discs (it will handle +R/+RW/-R/-RW.) When the Panasonic was returned (problem - would not record 16x DVDs properly), I started transferring the LiteOn recordings to the Panasonic for editing. One of these disks contained two programs, and when the later program had been transferred I erased it before trying to transfer the earlier program. After that, the earlier program could not be played back but was still on the disk. I was able to copy the VOB files in the VIDEO_TS folder to my desktop computer HDD (P4 86Mz XP SP2, EMC7.5 came with a Mad Dog DVD-RAM recorder) and was able to use EMC7.5 to copy to another DVD-R disk, which would play the entire program OK on the computer using Sonic Cineplayer. Then I tried to play the DVD on several other systems with strange results:

 

1. LiteOn would not recognize the disc as having any programs at all.

2. Panasonic would play the video but no sound.

3. Another Panasonic DVD player would play video with no sound.

4. A Sharp DVD player recognized it as a DVD but could not play it at all. This unit can play DVD's from either LiteOn or Panasonic recorders.

5. My laptop (1.7GHz XP SP2 with DVD-ROM/CD-RW drive and external DVD recorder) has both Nero 6 (came with external DVD-R drive) and Roxio 6 (retail version) installed. Nero player cannot play disk - just plays a snatch with sound and stops. Roxio player can play disc with sound correctly.

 

Then I tried to capture the video using DVD Builder. On the desktop, the program won't run, needs an upgrade to the video adapter to handle DirectX 9 3D; I contacted Sony about this and they tell me there is no upgrade currently available so I may have to buy a new video card. On the laptop, the Roxio 6 DVD Builder recognizes the sound as AC3 which it does not support, and which will result in the sound not being audible when played on a regular DVD player (which I think is the reason the Panasonic will not play the sound on this disk.)

 

Issues:

1. The desktop has enough memory & HDD space but is probably not fast enough to be much use for video processing. The DVD-RAM disk can't play DVD-RAM video recorded on the Panasonic recorder.

2. The laptop needs a larger HDD though with the Sony DVD-R drive can handle most media. There is not enough free space on C drive for caching the video. It can copy DVD's OK.

3. Only occasional use is required to recover data from the LiteOn recorder, nearly all editing done on off-air video is done on the Panasonic recorder, which has a HDD. Most editing is simply addition of chapter marks and elimination of commercials, pledge breaks and other extraneous content.

4. The LiteOn recorder is basically used as a last resort, as it has had a number of problems over the year I've owned it - mostly with DVD-R disks getting fried because it could not recognize that it had previously recorded a program to the same disk, then reformatted the disk. Without the HDD, this makes it next to useless for any recordings I want to be sure of capturing. Hence using RW disks makes sense as I don't have to buy many of them, and can re-use them once a program has been edited. Also the LiteOn audio quality is poor.

 

What I would like: A video converter that can take the VOB files, convert the AC3 audio, and dump the program onto a regular DVD-R or DVD-RW disk which can be read by the Panasonic or the LiteOn, complete with the sound. Is it worth upgrading to Roxio 9? Should I install this on the faster and more recent laptop?

I'd also like to recover the video files from the coasters made by the LiteOn. Any ideas welcomed.

One possible solution (is it?) would be to copy the video from the laptop via the IEEE1384 port to the DVD recorder (DV Cam input) and burn a DVD on the recorder from that input video/sound.

 

I have no idea if that would work.

 

You don't happen to have a digital camcorder, do you?

 

I have a Sony desktop (2.2 GHz) and invested in a AGP video card that has both AV, IEEE 1394 support and DirectX support. Of course, that meant that I needed a new sound card too. It was really easy to install. Onboard video and sound which my Sony had were not 'video editing friendly.'

 

I overlooked your comment about the laptop that has a 90% full hard drive. You might want to look into an external hard drive to store the files that you're not currently using.

You have the Basic Edition of EMC 7 which was included with your drive. According to the Roxio help

"You cannot capture Dolby Digital AC3 audio in some versions of Basic DVD Edition."

 

If you're having trouble running the basic edition of EMC7 on your computer, you'll probably have difficulty running version 9 because the computer requirements are higher for that version. Read the computer specifications for each version in order to see what you need. I don't know how old your computers are, but it might be cheaper to buy a new computer than to upgrade.

 

DVD Recorders record different types of files. The programs are geared to writing DVDs that will play on the most DVD Recorders...... capturing files recorded on DVD players is a different matter entirely.

Thanks, ml. I have posted to videohelp on this issue. At the moment, the newest computer in our house is about 3 years old, HP, 2.5GHz, 512MB RAM, Win XP SP1, but doesn't have a DVD recorder. My desktop (the one I referred to previously) is about 4 years old although bought "new" 3 years ago (store display model), and I recently upgraded from Win Me to Win XP SP2 and added the Mad Dog DVD recorder drive to it as well as a 250GB HDD and upgraded RAM to 512MB. But very likely the only way to get EMC7.5 DVD Builder to work is to add a new video card that will support DirectX 9/10. The laptop is 3 years old, and I am planning to upgrade its HDD as it is only 40GB and 90% full. Both desktop and laptop are Sony and have IEEE1384 ports. One possible solution (is it?) would be to copy the video from the laptop via the IEEE1384 port to the DVD recorder (DV Cam input) and burn a DVD on the recorder from that input video/sound. Neither laptop nor desktop has an A/V output jack, otherwise I could use it as an analog video source and record from it.
