burning mpeg-2 and ac3 to CD

[rork]

Hello,

I'm trying to burn a miniDVD on CD with the following method:
-captured and edited video with premiere/DV500 and rendered to Pinnacle DV video and PCM audio track.
-converted audio track to AC3 with Soft Encode
-Created VOB files from within ReelDVD (testfiles saved on harddrive)
-tested files with PowerDVD, works like a charm
-burned a UDF/ISO CDROM (AUDIO_TS/VIDEO_TS folders)as explained in tutorials, but cannot play the disk on my Thomson 4200 DVD player. It loads the disk and shows the play icon, but nothing happens. Is there anything I missed here??
Thanks for the reply,

rob

try burning just the video_ts folder...Not positive if this is your problem, but i found in the begining that burning both gave problems and the audio folder is probably empty anyway.

No, that doesn't work either. Gonna try another pack of CD's. Maybe that will help.

cheers,

How high is your bitrate??

If the Bitrate is too HIGH, data cannot be read fast enough from the disk - this is a rotational velocity / data density issue - because the data is not as densely packed on a CDR as it is on a DVD, the CDR cannot spin fast enough for enough bits to be read when a high data-rate MPEG file demands it, during playback. This is the reason that SVCD has a limited bitrate - it's not only for keeping the number of necessary disks down! The same issue exists with DVD content written to CDR/CDRW.

Also make sure that you are using decent quality disks, with a high index of reflectivity, since many standalone players have lasers which have difficulty reading CDRs (commercially-pressed CDs / DVDs have amuch higher index of reflectivity, thus requiring less power from the laser to read the bits from the disk).

I relaise you don't get a smuch capacity on a CDRW, but if you still have no joy, you might try authoring a smaller project to CDRW, as a tester, since many standalones findd these easier to read than CDRs. This is ironic, since CDRW has an even lower index of reflectivity than CDR, but the Laser wavelength required for reading CDRW is different, so this may be the reason for the anomolous behaviour. I'm not sure, but I think CDRW-reading laser wavelength may be closer to that required to read DVD than it is to CDR.

and a few dvd players that ive found that dont support minidvd seem to try playing the disc in VCD 2.0 format, where it just shows 00:00:00 and doesnt do anything else from there (says its playing tho)

Enf...

So far no luck. It could be the datarate, the player is just loading the disk and than stops. I tried CD-RW and CD-R's. Gonna try a SVCD project now. Thanks for all the help. It was also to see if my AC3 audio on the CD would be picked up by the amp. That it did through a powerDVD-cable-amp connection ;)

cheers,
