If you've already updated to a post-202 nightly, then you'll want to change density in build.prop.
- You'll need Root Explorer or another root file explorer. Go into the app's settings and make sure root or superuser is enabled.
- Navigate to /system folder by going up or back two directories from /sdcard.
- In /system, mount R/W. There will either be a R/W button up top, or an option under Menu > More.
- Long-press build.prop and "Open in Text Editor."
- Find "qemu.sf.lcd_density=161" just over halfway down and change it to 160.
- Reboot.
- Run Market.
- If you see a Movies category, you're done.
- If not, close Market, long-press your Market icon, Application Info > Clear Data.
- Repeat 7 thru 9 until it sticks.
