Thanks for the info... I think the bit rate is VBR but sort of high on the DMR vs say a PC capture card... on the 4.7GB drive I can hold about 6 hours more or less of high compression VBR stuff... formatted the 4.7GB DVD RAM's in FAT-32 come in about 4.25GB. The DMR 20 talks about a 22MB maximum data rate I think, but that may be as a result of duplexing (it can read while writing).
When I converted 22 minutes of a cartoon recorded at highest DMR 20 compression, it required about 400MB of space on a CDR broken into 3 parts with menus and what not... I'm not certain if one of the 3 segments was duplicated or not (as I mentioned it's still a bit confusing to me, and when formatted for DVD play well it isn't DOS and I'm unsure which files are put out thus cannot easily have a looksie for a duplicate mp3). It appears the 6 hour DVD RAM format of the DMR 20 DVD recorder can be copied by Panasonic utility to a DVD R... I will try later to play a DVD R created this way on a non-Panasonic drive with their utilities... it seems that 6 hours +- of decent quality recording on a single DVD isn't all so bad... lowering the data rate to 8MB seems to take a longish time... not sure what all is involved by my 550Mhz Celeron definately was hurting to get the rate reduced... also information on demuxing and on audio sequencing and what not... really I'm unsure what all it was trying to do but chug.
Thanks for your help on overscan... I'll look into the utility... I like the MP3 formatting being done by the DMR... everything comes out more or less easy to manipulate in a format which most of the applications seem to need/like. Now if only DVD camcorders drop in price:-o
For $800 as a video capture-->MP3 device I don't think the Panasonic DMR 20 is all that bad... I wish this stuff was discussed a bit more on usenet it appears DVD RAM has really no respect there... and while I understand DVD-RW is likely the one... I just don't understand DVD+RW as the 2nd place to DVD-RW...
I recall the beta/vhs wars, one thing I recall was the lower price of VHS and the greater availability of VHS generally than beta... it looks like DVD-RW is following the VHS model... if Panasonic has half a brain it'll try to include DVD-RAM with DVD-RW drives and make licensing easy... now a DVD-RW, DVD-R, DVD-RAM and CD-R, CD-RW drive... well hehe... I'll buy one!... or more:-o
