Here are some tips for ripping DVD's to digital format, so you can display on your DLNA enabled TV. The digital copy also forms your backup for commercial DVD's, but remember copyright rules mean copies of commercial DVD's may not be distributed.
The recommended software tool is Handbrake.
The recommended preset is "iPhone & iPod Touch" - this produces a reasonable size within reasonable time. For example, on a dual-core 2GHz machine with 4GB RAM, a typical 2hr movie will take about 40mins to rip a 1.2GB file, with minor pixelation.
Note the following options:
File format:
M4V (MP4) - allows aac+ac3, supported on iPhone & Samsung TV DLNA
MKV - requires 3rd party decoder on Apple OSX
Constant Quality:
20=good but large file
24=okay, smaller
Bit Rate:
1500=ok, minor loss
2500=hi quality (large file)
