Contrib: Attempt to repair .la pathes. Repeating things, because I don't know how to do it better... Anyway, just an attempt

- Put a limit on the SDP size
- Remove check for access_demux (this is not one, and it would crash later if it were anyway)
- Fix description to not assume this handles UDP only (since it does not anymore)

Add support for I422 streams (un tested).

 * deinterlace.c: compile warning fix.

Qt4 - Open Dialog. Implement start-time in advanced options. Cosmetic (enabling suffixes INSIDE spinBoxes) changes.

Transcode: We want to be strict when calling module_Need for audio filter, video filters and the deinterlace video filter too. (This fixes a problem with deinterlace not loading on my computer)

prefix which filters out input ports so VLC connects only to the
port(s) you want.

Patch from Paul Corke <paul.corke at datatote dot co do uk). It enables newer ivtv drivers to be used with the pvr input. Plus some additions and fixes from me:code cleanups, fix memoryleaks, coding style and identation fixes.
