First of all r7c is nice little program but in the majority of cases there is no reason to use it. I suggest you to try other stream recorders before even downloading r7c.

Pleae read Recording Real Media, Real Video and Real Audio streams to learn more about better alternatives of r7c.

R7C crashes after running out of memory
Recording time of R7C is limited by computer memory. Usually you can record from half an hour up to 2 hours depending on your computer. After running out of virtual memory R7C crashes. Sometimes even an increase of virtual memory doesn't help.

To solve this problem you can add a memory module (modules) to fit to your needs.

You may also try to download a clip in parts using start and end times like in the following example.
Original URL:

rtsp://somehost.com/somedir/01012004.rm

rtsp://somehost.com/somedir/01012004.rm?start=1:30&end=2:03:18

Can't begin decompressor (I420) (err=-1d 0h)
If you keep getting the following error

** Hardware decompressor found for I420 format
** Can't begin decompressor (I420) (err=-1d 0h)

If your system has a limited number of codecs you may install a new codec or even a codec pack like 'The codecs' fron ww.free-codecs.com. Note that only encoding codecs can be used as output codecs of r7c (decoding codecs won't help you here).

I can see "** Can't use DirectX 9.1... Preview will be in software mode". What does it mean?
It means it could not initialize DirectX for the preview window. It is not necessary because it can use GDI to show the preview. DirectX 9.1 is only needed for preview (for performance) and it is not used anywhere else.

I can see in log "Opening URL" and immediately followed by "Stop" and "Presentation closed". What's happened?
3 possibilities:

1. Your firewall blocks the internet connection. Try to check if R7C is allowed to access internet
2. The URL is invalid. Try to put exactly your URL into RealPlayer itself. If it cannot play it then you will not be able to convert it.
3. Your RealPlayer needs to be updated. As above, try to play this URL in RealPlayer itself.

The result is desynch.
Use a faster codecs encoder (or 'non compressed' codecs) and reduce 'Synch Error' in Options progressively to reach the best synch. THIS IS THE KEY for getting a perfect synch movie on slow computers so play with it without moderation. Another reason of the desynch could be the audio codecs, try to use another one or no compression if needed.

The output AVI is not complete.
It is probably the audio codecs you selected. Try to select another one (or no audio compression at all).

I want to convert a video/audio to a .MP3 only but i noticed the result is a bit faster (or slower) than the original
Try to set in Options, the original sound format you saw in the log when converting because the current MP3 encoder (BladeEnc) cannot resample the sound.

Can't enable the URL Fetcher at all.
You should not have this problem anymore because R7C can locate it automatically (remove 'options.ini' if necessary and restart R7C).
