bfginger: It is possible to watch recordings across the network directly from a Magic TV with 1lostkiwi's patch.
In VLC, go to Open Network Stream in the Media menu, enter the URL of the recording eg
http://192.168.1.68/1/ts/120312180000_003.ts
I have not managed to do this and as the mod is using webfs it probably isn't possible, happy to hear if anyone has managed. It is however possible to telnet to the box (part of mod too) so that might offer other options
The files themselves are chunked and so unless you have edited the recording and saved to disk (native MTV function) there is no guarantee that the entire episode is in only one file. We don't have a way to interpret the metadata on the MTV - so some prep. is required before any streaming solution provides a seamless solution
My approach is usually to edit the episode /program on the MTV (cutting ads trimming etc) then saving to the MTV - which creates a new (and identifiable file from datestamp) then I download this to my NAS for filing and watching later via my media streaming box (AC Ryan).
