Trouble with tivo to dvd

I have been trying to copy tivo to pc to dvd. I have a tivo ser.2, tivo desktop 2.3a, transfer the file and use videoredo to edit and then use convertxtodvd to re-encode. I have used convxdvd or clonedvd2 or dvdshrink or nero 6 to then burn to dvd+r/+rw.

The whole process seems to go well up to the point that when I try to replay the dvd in a sony stand alone dvd player the picture is jumpy, stuttered, out of sync or however else I might describe it whenever there is movement on the screen.

I then have taken the dvd back to my computer and played it and the picture looks fine in these areas, no jumpiness. I have even renamed the vob file to mpg and transfered back to tivo and the picture plays fine.

Can you help me, I'm at a loss.

Try a different brand or type of media since the DVD plays OK on your computer.

Have you looked at this thread on the TivoCommunity Forum? Search that thread for DVDStyler, gui4ffmpeg and VideoReDo.

Of course once you edit with VRD, you have a mpeg2 file which can be re-encoded and authored like any other mpeg2 (as you seem to be doing).

In case you haven't already realized it, always burn to file(s), .iso or DVD folder set., then burn to the DVD media. Can't beat imgburn for that last burn.

The R/W media have lower probability of playing correctly in a standalone player than the R media. I can recommend Sony or Verbatim 16X DVD+R from personal experience. Many people get better luck burning the 16X at lower speeds, either 12X or 8X.

I have tried both Verbatim +R and +RW and Memorex +R, both of these are highly rated disks. I have copied many a dvd using these brands and have never exp. any probs in the set top dvd. Burn speed is always set at 4x.

Have Imgburn and tried it also, same results. I have also tried playing the dvd in a diff. set top player and got same results.

The tivo file is ntsc 480x480 25.97fps recoreded in best quality from an antenna souce.

another possible thought...

Sounds like you've followed some good advice.

I would also suggest , just as a test, you save out of VRD with GOP=18 and then author or convert your file.
You'll find that at: Save As | Options | Max GOP Length
also, set the Bit Rate to 10.0 at the same place.

It will take 5x as long to save as usual, but this is just a test.
If this doesn't cure your problem, I'd seriously re-consider the burning technique, the blank discs, and the Sony player.

Oh, and never rely on a R/W DVD for anything, unless you have extensive experience with a particular burner, disc brand, and player, and even then, double check your work.
Most players are just not very R/W-friendly.

Last but not least, 480x480 is not a DVD format, and whether the Sony can handle it or not is unproven.
I had some 640x480 material that would just not play on any DVD players I tried.
However my usual 544x480 was fine, as was 702x480, and 720x480.

The 480x480 25.97fps was the tivo output and if I remember correctly videoredo changed the framerate to 29.97. Convertxtodvd changed the video size to 720x480 for the vob file.
I converted some 640x480 avi to 720x480 and burned to dvd which played back fine on the sony player. This all leads me to believe that it has something to do with the 480 to 720 conversion.

Are you sure??

I think your TiVo video must have been 480x480 at 29.97 fps.

I can't fault your process. All I can tell you is what I do that works:
1. Edit with VideoReDo, Save as either .vob or .mpg .
2. Re-encode with gui4ffmpeg (free download from videohelp.com). My source is 352x480 at 2.7 Mbps with mp2 audio. I re-encode to 720x480 with AC3 audio at 4.0 Mbps. In gui4ffmpeg select NTSC and set the desired bit rate. I would recommend something slightly higher than whatever the source bitrate is. Also, add the following switches to the options:
-flags ilme+ildct -top 1
This forces the re-encoding to maintain top-field-first (TFF) interlacing which is in your TiVo source file. (You can check this with gspot if desired.) Maintaining interlace is important for avoiding motion artifacts when the DVD is played on a typical interlaced TV. For my parameters and computer the re-encode time is 113% of the video duration.
You now have a totally NTSC compliant ("D1") mpeg2 file which should be processed by any authoring program without re-encoding. I use DVDStyler, free, just Google. I have also input these files into MyDVD in Roxio Easy Media Creator Ver. 9 with good results except for occasional slight audio sync problems (correctable in VRD if desired).

I believe there are two possible bitrates for your source files, around 3.5 Mbps and 5.8 Mbps (TiVo "high" and "best" qualities). VRD tells you what the true bitrate is in the information it displays upon saving a file.

A BIG Thank You to dlflannery!

This tivo to dvd picture problem was driving me crazy trying to find the answer. I followed your directions and the dvd plays perfectly now on tv.

I was using another program to convert to dvd and I guess it just didn't check to see if the interlacing should be preserved. I thought that when a program touted itself as being one that could handle all kinds of conversions and even specifically named tivo as a file it could handle that it would have handled it correctly.

In all modesty

Well, thank you, thank you .... no need to applaud folks. I've got my fingers crossed. Does this mean I get the blame if his next DVD is bad ? :rolleyes:

Anyway, glad to help, trimjim, and may the good luck continue!
