Is there a way to convert 352x240 to 352x480 without re-encoding?

I use a tool that can take a file that meets these specs:

Resolution: any valid MPEG-2 width, 480+ height
Framerate: 23.976, 29.97 and 59.94
Bitrate: 2-8Mpbs CBR/VBR
Audio: 48KHz @ 112-320kbps, MPEG-1 layer II

and prepare it for importing into a program called DVArchive, which can stream video files to my 5000 series ReplayTVs.

I don't have a problem with higher resolution S(X)VCDs that are 480 vertical resolution. Unfortunately, I have a small number of videos that are in VCD format, which has a 352x240 framesize. I don't have any problem converting them to MPEG-2, 48 KHz audio using svcd2dvd (at http://www.svcd2dvd.com) without re-encoding. The trouble is, if I want to convert them to the required 480(+) vertical resolution using Womble (MPEG-VCR v3.13) or TMPGEnc Plus 2.5, the file gets re-encoded, taking a lot of time and considerably reducing the quality.

Is there any way to convert from a 352x240 framesize to a 352x480 framesize without re-encoding and/or losing considerable quality?

Thanks,

Tim

Simply put....NO!

Why do you want to change it to x480? You can put x240 on dvd, no need to convert it. I've never tried this but I read in a thread that if your vcd (mpeg1) has a bitrate of at least 1850 you don't need to convert to mpeg2.

If you must have x480 then just patch the 240 to 480 with dvdpatcher, compile your dvd and before you burn patch the vobs back to 240.
This is covered in the guides and all over the forum.

This would be for dvd, I noticed your wanting to do this for streaming to replay, is the first program your using even creating dvd or just an mpeg? Is the second prog just playing a dvd source off your hdd and streaming to replay?

I know I put this post in the DVD authoring forum, but I don't want to burn it to a DVD (I can already get it ready for that using svcd2mpg) - I want to be able to stream it to my ReplayTV so I can view it using the Replay's interface to the TV. The only way I can stream it to the Replay is if the vertical resolution is 480.

Maybe I can use dvdpatcher to change the header to show 352x480 and trick the rtvconvert tool into preparing it for streaming. I'll have to give it a try.
