Just curious what others think/have done. I converted all my DVDs (and now Blurays) to MKV with MakeMKV over the years and have amassed several terabytes of data. I was originally using a net top with XBMC and using these files for "lossless" playback. However, now that I've gone the ATV route, and converted everything with handbrake, all my MP4s fit on one 2 TB drive. Should I delete the (rather large!) MKVs? On one hand, it's not like I currently need the space and maybe some better format comes along (or native MKV support on ATV) in the future so it makes sense to hang onto the files. But, as I need more space, it's tempting to simply delete the MKVs (the handbrake conversions really look quite good to my eyes) rather than buy even more hard drives! Anyone else have a similar debate or other thoughts? I guess to delete and re-rip with makeMkv if needed wouldn't be the end of the world but I'm a bit paranoid (what if I lose the disc, gets scratched, etc) - plus, it took a long time to rip!
