+Understood. Let's implement a **clean, methodical approach** using two reliable Linux CLI tools to rip DVDs. We'll compare:
+
+1. **`vobcopy`** (traditional, reliable)
+2. **`dvdbackup` + `ffmpeg`** (more flexible)
+
+Both methods will output MKV files for fair comparison.
+
+---
+
+### **Method 1: vobcopy (Simple & Reliable)**
+```bash
+# Install if needed
+sudo apt install vobcopy
+
+# Create mount point (if not already done)
+sudo mkdir -p /mnt/dvd
+sudo mount /dev/sr0 /mnt/dvd
+
+# Rip main title (longest track) to VOB
+vobcopy -l -n $(lsdvd /dev/sr0 | grep 'Longest track' | awk '{print $3}') -i /mnt/dvd -o ~/dvd_rip
+
+# Convert VOB to MKV
+ffmpeg -i ~/dvd_rip/*/VIDEO_TS/merged.vob -c copy "method1_output.mkv"
+
+# Cleanup
+sudo umount /mnt/dvd
+```
+
+---
+
+### **Method 2: dvdbackup + ffmpeg (More Control)**
+```bash
+# Install if needed
+sudo apt install dvdbackup
+
+# Rip specific title
+dvdbackup -i /dev/sr0 -o ~/dvd_rip -t $(lsdvd /dev/sr0 | grep 'Longest track' | awk '{print $3}') -M
+
+# Convert VOBs to MKV
+ffmpeg -i "concat:$(ls ~/dvd_rip/*/VIDEO_TS/VTS_*.VOB | tr '\n' '|' | sed 's/|$//')" \
+  -c copy "method2_output.mkv"
+```
+
+---
+
+### **Comparison Script**
+```bash
+#!/bin/bash
+DVD_DEV="/dev/sr0"
+OUTPUT_DIR="$HOME/dvd_comparison"
+mkdir -p "$OUTPUT_DIR"
+
+# Method 1: vobcopy
+time {
+  sudo mount "$DVD_DEV" /mnt/dvd 2>/dev/null
+  vobcopy -l -n $(lsdvd "$DVD_DEV" | grep 'Longest track' | awk '{print $3}') -i /mnt/dvd -o "$OUTPUT_DIR/method1"
+  ffmpeg -i "$OUTPUT_DIR/method1"/*/VIDEO_TS/merged.vob -c copy "$OUTPUT_DIR/method1.mkv" -y
+}
+
+# Method 2: dvdbackup
+time {
+  dvdbackup -i "$DVD_DEV" -o "$OUTPUT_DIR/method2" -t $(lsdvd "$DVD_DEV" | grep 'Longest track' | awk '{print $3}') -M
+  ffmpeg -i "concat:$(ls "$OUTPUT_DIR/method2"/*/VIDEO_TS/VTS_*.VOB | tr '\n' '|' | sed 's/|$//')" \
+    -c copy "$OUTPUT_DIR/method2.mkv" -y
+}
+
+# Compare results
+echo -e "\n=== RESULTS ==="
+echo "Method 1 (vobcopy): $(du -h "$OUTPUT_DIR/method1.mkv" | awk '{print $1}')"
+echo "Method 2 (dvdbackup): $(du -h "$OUTPUT_DIR/method2.mkv" | awk '{print $1}')"
+```
+
+---
+
+### **How to Evaluate**
+1. **Speed**: Check the `time` output for each method
+2. **Quality**: Compare files with:
+   ```bash
+   ffprobe -v error -show_streams -i method1.mkv > method1_info.txt
+   ffprobe -v error -show_streams -i method2.mkv > method2_info.txt
+   diff method1_info.txt method2_info.txt
+   ```
+3. **Reliability**: Note which method had fewer errors
+
+---
+
+### **Final Recommendation**
+- **Choose `vobcopy` if**: You want simplicity and reliable single-file output
+- **Choose `dvdbackup` if**: You need per-title control or have problematic discs
+
+Both methods are **bulletproof** when discs are clean. The winner depends on your specific use case.

 Great! The DVD is now properly mounted at `/mnt/dvd` in read-only mode (which is normal for DVDs). Let's proceed with the **simplest, most reliable method** to extract **Title 06** (the 2h15m episode) using your working setup.
