What format are your videos and what exactly is that Archos device? If it's an HTPC, you may not need anything.
Dunker. You obviously live in the USA, I live in the UK. AV media players both disc and hard drive are becoming very popular here. The various models of Archos media players, mine the AV700 has a 40 GB HD there is also a 100GB version plus many other models.( www.archos.com )are able to store on a hard drive and play on a built in TFT screen MPEG4 AV files and can also store data. They can convert DVDs or AV signals from DVD tape players and the AV output from TVs via a converter pod that pluge into the media player.
Yeah, haven't seen those yet. I'm sure we'll get 'em in the next year or so. As to your original question, though, and assuming you didn't start with MPEG-4 or WMV9 to begin with, it should do the job. It should meet the AV700's specs. You could also use VirtualDub, and you would probably use one of the Microsoft MPEG-4 codecs. http://www.ipod-video-converter.org/
Since my original post I have found an excellent piece of free software for converting video files into MPEG4 format. It can be downloaded from http://divx.ppccool.com/langue.php?lang=EN It can covert files that will play on the following:- Smartphone, PDA, Palm Tungsten, PC, VGA(E500), Archos various models, Gemsoc Media Jukebox, iRiver H340, iRiver PMP100 and Homecinema. Some of these I am not familiar with. You can alter various settings to alter video and audio quality, output dimensions, clip duration etc. I have used this to re-encode a number of DVDs to play on my AV700 and all I can say is I am very pleased with the results.
I have a video file in QT format which can only be played back from the iTunes software. Does any one know of any software that I can use to burn this onto a DVD? I tried Nero 6 and it didn't work.
I think ConvertXToDVD or WinAVI, but those are partly-functional payware. Try SUPER first, since it's free.
