Hi, I have copied 10 family video VHS tapes to DVD (Sony combo unit) for in-laws as I thought that was best solution. However it took me 3-4 DVD's per tape and as I'm reading on forum DVD's will be obsolete soon. Instead of handing them 40 DVD's I would like to purchase them an external HD that I can put the movies on so they will be able to connect the HD directly to TV and watch movies that way. They would also be able to share HD with extended family to copy videos to their own HD or thumbdrive. Which format would be best to use for this? For instance, I put a VOB file and an MP4 file on thumbdrive plugged it in to TV. The VOB was able to play but the MP4 was not. Which format would be most universal for play on TV? MOV? WMV? MPEG? I would probably only be doing a little editing of the VOB files I have; each VHS tape is on 3-4 DVD's so I would want to create 1 video file per VHS tape and perhaps edit out a few "snow" scenes. Editing could be done on Imovie or Windows Movie Maker. I have PC and MBPro (2008 version with 4GBRam) and a lot of the software that is talked about in forum. Thanks for your help in advance!
