Sorry for the extended time to reply... :o
I see what the problem is now. Rather than have Nero take the time to do all that re-encoding of the non-standard DVB-T MPEG2 files, you would like to burn the bare MPEG2 files to disc rather than author them as a DVD-Video. Then you need a player to play these back.
Looking at the Philips 5960 specifications, it mentions MPEG2 as a playable compression format and DVD or CD as a physical medium, but this could just be DVD-Video or SVCD (CD) and not bare MPEG2 files burned as data on a DVD. Usually the thing to look for in a player is the ability to play a VOB file (essentially a segment of the full authored movie but residing as a bare MPEG2); however the 5960 doesn't appear to have this.
If you find a player that will read bare MPEG2 files, another problem is the size of the MPEG2 files permissible. As long as they are less that 2 GB then that should be fine, but otherwise they need to be burned to DVD using the UDF template of Nero. Even having done that, they may not be readable by a player past the 2 GB mark so you'll need to author to DVD-Video in order to view them.
I also record a lot of stuff from Freeview, using Hauppauge DVB-T cards, and have found it's best to make your life easier by using a good software TV/recording application. The Hauppauge WinTV2000 is rubbish, and couldn't save a decent MPEG2 file to save its life. If you want something good then you should try DVBviewer, which cost about Â£10 and makes MPEG2 recordings that need no conversion when authoring to DVD. You may have to re-establish the group-of-pictures intervals on the recordings, but this can be done very easily since you already have VideoReDo and its Quickstream Fix utility.
In summary: I think your idea of saving recordings less than 2 GB as data on a DVD is good, providing you can find a player because I doubt that any of the currently available Philips models will do this. However you will probably have to consider authoring any files greater than 2 GB, and having a decent TV application for the PC will save you a lot of time. Can I ask which DVB-T card you use, and which software?
