I was wondering about if it would be possible to output video/audio to a D-VHS recorder.

Specifically the JVC HM-DH40000 (http://www.crutchfield.com/cgi-bin/S-bMMkb09ErZM/ProdView.asp?a=&s=0&cc=01&g=55900&id=detailed_info&i=257HMDH40K).

I have some Windows Media 9 files that I'm unhappy with the material after converting/compressing it down to fit on a DVD and figured via firewire and maybe using the WM9 Enocoder I could transfer them to tape but get better quality that S-VHS.

TIA

Moved from analog capture forum to HDTV/DVB forum.

According to the specificatios of your recorder:

i.LINK Connections: There are 2 i.LINK connections on the unit's rear panel labeled "i.LINK In/Out" and "DV In". i.LINK is a digital serial interface that allows devices so equipped to exchange digital video signals, digital audio signals and device control signals bi-directionally over a single cable. This VCR uses four-pin i.LINK connectors to input and output MPEG2 video signals, audio signals, and control signals. The i.LINK connector is also used as an input for DV compressed signals from the DV output of a digital video camera; although this unit will accept DV signals from DV and Mini DV camcorders, it cannot output signals in the DV format.

If your PC has firewire connection you can convert your video to DV avi format (using a DV codec) and then transfer it to your recorder using DVIO, Scenalyzer live or any video editiong software that can output to tape.

that doesn't seam right though. dvd is worse than S-vhs? No. if you have a raw .avi file and put it on dvd you shouldnt see any loss in quality.

Yeah, I've given up on that idea.

Thanks

You can encode your source video into one of the MP@HL mpeg2 formats used to broadcast HDTV, such as 1920x720p or 1440x1080i,

then you'd encode your audio into mp2 or ac3,

then you would use some expensive mpeg transport stream muxing software to mix the resulting multigigabyte video and audio elementary streams into a transport stream,

then you'd use software such as dvhstool or capdvhs to transmit the
transport stream to your dvhs deck.

Everything is fine, except I don't know of any free mpeg2ts muxing software, or any free MP@HL mpeg2 encoders - not anything with any kind of performance, anyway.

I don't know if 40k will take "DV" input, if it does, you might want to look into encoding your video into 720x480@30fps DV and record that using dvapp from dxdsk or something similar, but of course, you are not going to be getting any high quality with this method.
