Readynas & DLNA...

Folks -

I'm new to all this and trying to catch up. I have ready thru several forums and did a search on threads around Twonky.

Here is what I have..

Readynas NV+ - (currently housing photos, music and video)
Readynas Pro 6 - (future home of photos, music and video)

Pioneer Kuro TV's / Panasonic Plasma / Ipad's / Iphone's / Itouch

Here is what I am trying to do:

- Stream 10 years of Home Movies stored on NAS (ACHVD, and other formats). Most are HD Def.
- Stream Ripped DVDs - most are NOT HD.
- NOT insert a Desktop / Laptop / Media Player or other device into the process.

Here is my problem:

- All TV's have DLNA players built in
- All TV's can connect to NAS and see movie Titles listed
- MOST of the movies can not be played by the TV.
- Iphone / iPad running a DLNA player (8player - but open to suggestions) can connect - but not play HD resolution Home Movies.

Here seem to be my choices:

- Change all the movie formats to something the TV's, iPhones, iPads all seem to like
- Insert a media player like Twonky on the NAS to resolve above

Here is what I don't know:

- Will Twonky resolve the above issues w/ formats - or do I need to recode everything
- What resolution can Twonky support (1080p?)
- What formats can Twonky stream?
- What is the latest version of Twonky (5.1.5 or 6.0.32??)

Thank you again for the help and wisdom.
