The do. I'm currently uploading some quicktime videos to show you the
differences. Both time it's a digital recording. The sound you hear
in the background is the digital out of the Archos fed thru my MD

See "" - for the Archos - for Rockbox. (I didn't press play to start the recording
until after the clip - the peak meter does not change when I start it

Yep, at least after each longer recording. See ""

Here I stop a two hour recording and play it back right away.
Stutters three times (at :20) and then starts... afterwards I try to
confuse the machine by forwarding which had caused trouble the last
time... [sorry, this clip is so dark you'll have to turn up the
brightness on your screen]

Here's another short suggestion. Unlike the Archos firmware you do
not turn off the input when I stop a recording. This is really useful
- because I can still hear the source and already get ready for the
next recording.

Can we have a similar thing for the recording source selection menu
as well? I would welcome if you put the selected source on the
headphones while you're in that menu as well.

You can be shure to hear more from me... I bought the Archos because
it could record and I'm fed up with it crashing half of my overnight

BTW, the fist two 1/2 hour recording seemed OK - couldn't record
longer as the batteries were almost empty. I edited it in with
mp3directcut and there was only one very small drop out (which might
have come from the satellite source) - apart from that everything
seemed OK.

How is the behaviour for low batteries at the moment? Do I have to
watch them closely or will the unit turn of soon enough?

The next long recording is running, if anything worth mentioning
happens, I'll post that.
