1. I use handbrake to convert mkv videos (which have already been encoded) to play on my atv2, if i use the atv2 preset the framerate is ntsc but i live in the uk so have a pal telly, should i always set it to pal, ntsc or same as source? 2. I like the quality to be as good as the original on my 50 inch plasma to me its important, is the best way to set the target size same as the original, size is not an issue for me as i delete after watching often, or will a larger file size cause the streaming too many problems. Also should i use rf (constant quality) instead or average bit rate. I tried rf 18 and was dissapointed with the pq. 3. Only just having bought my atv2 I was converting to mp4, putting that on a usb and playing on the ps3, worked perfectly although a little cumbersome. But now handbrake makes m4v files and wont let me put them on a usb, how can i make the files mp4 s again(preferably right from the start, i dont want to convert m4v s to mp4s, but mkv s to mp4. Thanks for looking and thanks for any help!
