I want to know if it's possible to re-encode an already encoded video (but this time, having wpredp=0) with the following requirements:
(1) no quality loss
(2) output video size must not vary that much from the original; say 100mb (approx.) increase is fine. I mean, cuz I don't think that wpredp=2 is a major contributor to the compression of the output video right?
I've used mkv2vob and it has accomplished requirement (1) but not (2). The output video size became 1.5x the original.
I need to know if there's a way because this "wpredp option" is causing the video to pixelate and stutter on my PHILIPS BDP-7500.

you have to re-encode and you will lose quality
just re-encode the original source video (i.e. don't start from the encoded video)
Thanks for your reply,
I don't have the original source of the video, nor do I have that much free space on my computer to convert the video to a lossless compression format and then re-encode it with wpredp=0.
There has to be another way.
No there isn't. You have to re-encode the encoded video then, and suffer the loss
Decompressing to a lossless format doesn't provide any benefit here , and your player won't play a lossless format (lossless means equivalent to the encoded video, not the original source video - it doesn't recover the lost details or eliminate compression artifacts, and when you re-encode you still incur the generation loss) . Just re-encode directly from the encoded video.
Search for a firmware update on your player. Some companies have updated firmware that allow weightp compatibility e.g. oppo has done this for their BD players
