DVD Recording

By colinabbott ·
I have dual Win XP Pro and Win 98 SE operating systems on my computer with a VisionPlus Digital TV Tuner PCI card. I wish to record live broadcast TV programs direct to a recordable DVD disk via a LiteOn Dual Layer DVD Rom without first of all recording to the hard drive.
So far I have been unable to find suitable software that will enable me to do this. Is it feasible to record direct and if so how can it be done. I would be most grateful for the answer.

Kind regards

Colin Abbott

The issue with recording to DVD from a live broadcast is the process of encoding the video to the MPEG format used on DVDs.

You need lots of RAM, (1GB or more) and a fast CPU.
Or a dedicated hardware solution.

The next problem is running the DVD recorder at a 1X speed.

In fact, thinking about this, you would actually need to record at less than 1X speed to avoid buffer under-run problems.

If the CPU is busy servicing a high priority interrupt, there can / will be gaps in the data stream to the DVD recorder.

So, you need to simultaneously:

Capture the video and convert it to digital;

Buffer the data stream for the MPEG encoding process;

Buffer the encoded MPEG data to the DVD recorder;

Record the video data to the DVD.

Not sure off hand just how fast a system you would need to accomplish all of that in "real" time.

I'm wondering why you want to bypass the hard drive. That is the only part of your scenario that makes it tricky.

I have 3 dedicated media boxes (ranging from a 1GHZ P3 to a 2.8GHZ P4) and all of them can handle recording TV to a hard drive and then burning to DVD later. Plus, this option allows me to edit out commercials if I want.

I guess I'm not really answering your question in terms of which software to use; however, it may be easier in the long run to record to HDD then DVD.

Actually the cheapest and easiest way to record directly to disc would be to pick up a standalone DVD burner (which are under $200) and just eliminate the PC altogether.

BTW, I failed to mention that Sage TV is a nice PC-based PVR app that you could use to schedule and record your programs to the HDD. I think it runs around $60.

I tried it out about a year ago and it was pretty nice. It couldn't beat my TiVo's interface, though, so I don't use it very often.

This is just a thought, but a major part of streaming movies is the bit rate at witch they move, The buffer on the drive will not be able to keep up with this speed. On Nero one may create a temporary image of files to burn that after they are burned they are deleted. DVD shrink will offer a way for compression of VOB, but if you are streaming and recording into WMV, then just save it as a temp and delte it after. This wll also allow you to cut and re-engineer the movie. Just trying to help
