Thank you Hkan! This morning I was able to get a copy of the .mwv file in 428 x 240 resolution and it played fine – a bit fuzzy on my 42” HD plasma TV, but it played. Turns out the larger file is 856 x 480 – just a little over the maximum 720 x 480 the DV-400 will play. Next, I’ll see if I can get the original 856 x 480 file saved to as close to a 720 x 480 resolution as possible to maximize the available image resolution.
I have another question/problem. I’m having trouble getting the DV-400V’s upconversion to work with my 5 year old Sony KE-42TS2U plasma TV.
My understanding is that to get upconversion to work, I have to hook up using HDMI. My Sony plasma TV is 5 years old and doesn’t have an HDMI input, but does have a DVI input. So, I was sold an “HDMI to DVI” cable and was told it would work – just need to also use a set of RCA cables for the audio, which is not a problem. I was also sold a DVI switch box because my Sony plasma TV has only one DVI input – and I need to share that DVI input with the DVI output of my digital HD cable box.
My Sony TV plasma supports up to 1080i and 720p – but (and I believe this is the problem) apparently the maximum resolution that Sony plasma TV will display is 1024 x 1080i or 1024 x 720p. So, when I hook the DV-400 to my Sony plasma TV using the “HDMI > DVI” cable, the only HDMI resolution that “works” is 720 x 480p. Trying to manually set the DV-400 to any other resolution (e.g. 1920 x 1080i or 1280 x 720p) simply causes the Sony plasma TV screen to go black (and then I have to reset the DV-400 back to it’s initial setting using “Standby |<<”.)
My understanding is that my Sony plasma TV downconverts the higher resolution digital HD cable box’s 1080i or 720p signals arriving through the TV’s DVI input to accommodate the TV’s maximum 1024 line resolution, but for some reason, it seems it won’t do that for the DV-400’s incoming signal…
Or - am I missing something?
Even though I thought that to use the DV-400’s upconversion at all I had to use the DV-400’s HDMI output, when I hook up using “Component” cables instead of the “HDMI > DVI” cable, I can manually set the DV-400 to “Progressive”, and seem to get the same 720 x 480p setting as when using the “HDMI > DVI”. So, I suppose in my case there’s no need to use the “HDMI > DVI” cable/DVI switchbox after all…
Is this all correct, or:
1. Is there any way I can successfully upconvert to anything higher than 720 x 480p?
2. If not, is there any other reason why the “HDMI > DVI” connection would be preferable to the “Component” connection? (If not, I might as well return the “HDMI > DVI” cable & DVI switchbox, which the vendor told me I can do, and use the “Component” connection instead…)
