ISO9660 Limit in ImgBurn Support Posted April 7, 2009 It doesn't matter what disc format you use (DVD, HD DVD, BD), UDF is the only (common) file system for optical discs that supports single files >= 4GB in size. You don't want to convert HD content to DVD Video, you'll lose all the benefits. So basically, yeah you're left with buying a little media player. I've heard of the popcorn ones but never really seen them. I have seen/tried the Western Digital TV one though and I think they're pretty cool. Get yourself one of those and a little external hdd or big usb memory stick (16 / 32GB) and you're all set. I guess my other option is to split the large files into multiple smaller files >4.7 GB and burn multiple DVDs. Since DL DVD's are so much more cost wise then regular DVD's this may not be a bad idea on my part. I've heard the WD are good but since I already have a wifi network setup the Popcorn would be great and besides it's built on a Linux OS (at least that my understanding). I already have a 320GB external HDD and a 1TB external HDD which is around half full now. Thanks for your help and responses though. We'll probably laugh at threads like this 10 years from now at the fact that we were discussing physical media and different ways to do things with it.
