Hi Just18,
thanks for going to all that trouble.
Are you running the conversion through the commandline ?I've recently quit windows altogether, I don't regret it but are inclined towards using a GUI .A few weeks back I converted 10 to 15 .mp4's, and .flv's to .avi. just using the presets in WinFF.
Really simple.
I use them then on a USB flash drive on my Digital T.V. , in the comfort of the lounge room

So figuring what has changed has me stumped.
I also upload compositions recorded using Audacity, and Videos (webcam quality) to Youtube. Thus the need for converting file types.
A small problem can take me hours of reading to learn the general environment I'm working in, and finding a fix. Obviously we all go through this learning stage.
The 'Man Pages' is somewhere I should be looking, thanks for mentioning.
I would be interested to know, if you don't mind, how you tried the conversion of the /Led_Zepplin.flv to .avi, as you say: "I didn't yet try it from WinFF itself."The conversion of files that size would take 5 to ten minutes generally using WinFF.
I take it (guess) that the ffmpeg, and Lame, are the 'applications' that actually do the work, converting Video and Sound ?
Wondering if installing another program that uses those Apps could 'upset' another program, i.e. WinFF ?
Lots of questions, sorry.
I should mention I'm using PCLinuxOS 2011 MiniMe, and LXDE.
Intel 2.6 Ghz cpu
1 GB RAM.
I joined the Google group, WinFF, haven't had time to read much as yet.
http://groups.google.com/group/winffWould I be right that you ran commands in a Konsole for your test ?I know this is probably a really simple problem, and that reinstalling may fix WinFF, however I did try that already. Figuring the commands is obviously the best way to go about fixing, or re- setting the presets.
Before I do anything with the above info ...... I noticed there are updates to some relevant packages today (for me) so it would be best to fully update to be sure you have those. I am not sure they make a difference, but it would be best to be sure.
Yes, I've had some updates also.
Will keep researching and trying to get some Video Converter working, don't want to install any more programs though.
Minor problem, but when something doesn't work I get a insatiable drive to make it work.
I'm sure you know what I mean

Thanks again Just18, if you have any further interest I'd be pleased to get your feedback.
