Thanks for providing the new 0.98 build. I am using your builds on an ancient Win98 box... usually they work great, but I noticed with this one (as opposed to the previous build) I am getting errors (visually) in the output. When playing back transferred videos on my Tivo I am getting breaking up in the picture that looks similar to a poor quality cable or antenna feed.
I went back to the previous build and verified that the same video transfers fine using that build. |

Hrmm, can you post the output of:
| Code: | ffmpeg -i "<filename>" |
And have you tried rebooting your Tivo and then doing the transfer with the new build.
It might sound silly, but when my last Tivo hard drive went bad some transfers would show the digital block breakup while others worked fine. It all depends on where on the hard drive it was writing the transfer to.
The real way to tell is to look at the debug log on console and note the ffmpeg transcode command line that pyTivo is using. Then transcode the file manually saving it to your hard drive and watch it on your computer to see if there is the same output errors. If so, then it's the build's fault, if not then your Tivo is acting up. |

| Any quick tips on how to capture or cut and paste the output of ffmpeg -i on win98? Most of it scrolls off the screen, and when I tried to redirect it I find win98 doesn't support 2> |

Can I ask why you're using Windows 98?

Right click in the Command Prompt window and choose Mark. Then you should be able to highlight the output, right click and choose Copy, and paste here.
Or at least that's how you would do it on XP. |

On my XP machine, that second right click must be on the border rather than inside the window, and you have to select "Edit" then "Copy".

| I stand corrected. Guess I shouldn't try to give instructions from memory... |

Using the Mark option was the first thing I tried, but most of the output has scrolled off the top of the screen and there is no scroll buffer apparently in this awful win98 shell.
This is just an ancient old pc I pulled out of storage last year to use for handling video transfers because my main machine (laptop) developed a failing fan and tends to overheat under long steady loads and I'm not going to bother replacing it because you have to completely dismantle it including the motherboard to get at it (thanks Dell!).
So yeah, I'm just cheap 
Am I correct that moving ffmpeg and the video over to my XP laptop and running it there would not give you the output you want to see? |

| By the way it wasn't just one video giving problems with this new build. All 3 in a row I tried with it did it. Then all 3 were fine using the older build. |

Grabbing the info from an XP machine is fine. I'm trying to figure out what type of video and audio you have so I can trace what has changed in ffmpeg that is causing the problem.
The real test would be to manually run the transcode command that pyTivo is using and see if t he resulting vob shows the same error on 98 and XP. Just trying to rule out Tivo side issues. |

| And wmcbrine's suggestion is a good one. Running Linux on that old hardware might actually give you better performance for pyTivo transfers. Win98 wasn't terribly efficient. |

Here's the ffmpeg -i output on my XP machine. I actually have a very old SUSE linux dual boot setup on that win98 box so may experiement with linux.

I did a couple more test transfers of the same file using the new build and this time both transfers had no problems or video glitches.
Pretty sure this old win98 box is on its last legs or something. At any rate, ignore my prior bug report.
I think a nice quad core laptop early next year is in my future. |

You know, the other night, I transferred a file with no reported errors, and it came out full of glitches. I deleted it and redownloaded it later, and it came out perfectly. I suspect a TiVo-side problem.
