## ⚠ Legal Considerations

- **YouTube ToS**: Be aware of YouTube's Terms of Service regarding content downloading
- **Fair use**: Consider fair use principles in your jurisdiction

## 🛠 Troubleshooting

### Common Issues

**"yt-dlp not found" error**
- The script should install it automatically
- If not, manually install: `pip install yt-dlp`

**Permission denied errors**
- On Unix systems: `chmod +x youtube_archiver.py`
- Run with appropriate permissions

**Network/download errors**
- The script continues on errors - check the output for specific failures
- Some videos may be unavailable due to geographic restrictions or privacy settings

**Python not found**
- Ensure Python 3.6+ is installed and in your PATH
- Try `python3` instead of `python` on some systems

### Getting Help

If you encounter issues:
1. Check the console output for specific error messages
2. Ensure you have a stable internet connection
3. Verify the channel URL is correct and publicly accessible
4. Try running with `--quality worst` to test with smaller files
