I have my DTIVO series 2 networked and ty streems download to my pc without any problem.
When I try to create an mpg file (file Multiplex files and Multiplex files new format) I get this log:
Detected Tivo Type: Series2
Detected Audio Stream Type: MPEG Layer II
Final standardAudioSize = 592
Final standardFrameLength = 576
Final standardAudioDiff = 2160 or 00:00:00.024
First Video PTS: 00:03:54.382
......... 100......... 200......... 300......... 400......... 500

......... 600......... 700......... 800......... 900......... 1000

......... 1600......... 1700......... 1800......... 1900......... 2000

......... 2100......... 2200......... 2300......... 2400......... 2500

......... 2600......... 2700......... 2800......... 2900......... 3000

.......

DiffTime = 19.234001 (19234) == 0.320567 Minutes

total = 402522112 (383 MB)
When I play the mpg using Windows media player there is no delay, HOWEVER when I create a DVD audio starts progressively getting out of sync. Is there a way to fix this? If so what tools to use? I've tried just about every setting withing TyTools without any luck......
PC I'm using has a 3.2 GHz P4 and 1GB ram so that should not be an issue.
thanks,

More information would help in diagnosing this. Here are two questions from my own travels...

1 - Are you "patching audio holes"? I seem to recall this helps keep things in sync.

2 - How are you authoring the DVD? I use DVDLab and find that when I "rewrite GOP timecode" it sees some offsets when the editing is done in TYTool.

My work flow is TYTool to get .ty (patch audio), edit in TYTool and multiplex (no transcoding). Load into DVDLab and demux, rewrite GOP timecode, transcode audio to ac3, master with DVDLab using alternate engine then burn via Nero 6.x.

Good Luck,

I've tried with patching the holes and without it....the video comes in 23.976 fps format. If I play it using Widows Media Player on my pc everything is in Sync 100%.
Once I load it into my DVD Authoring program (DVD Architect-Part of the Sony VEGAS 5 suite) I can notice that sound is faster than the picture....

Thanks for any ideas or suggestions.

Try using a DVD authoring program that's been proven to work without issues when using it with mpegs created from ty files. It seems like every other day someone is complaining because they're using a program that's been untested with ty mpeg files. Ty files are non-standard mpeg2 files and can cause all kinds of problems with off-the-shelf commercial authoring software. TyTools by itself should be able to do whatever you need to create basic menus and such for a DVD compilation. If you need something fancier then give DVD-Lab a try as it works well with non-standard mpegs such as ty files or Dish PVR files.
